Opposite angles of a parallelogram are equal (or congruent) Consecutive angles are supplementary angles to each other (that means they add up to 180 degrees)
Are consecutive angles of a parallelogram are supplementary?
Consecutive Angles of a Parallelogram are Supplementary
Given: ABCD is a parallelogram, with four angles ∠A, ∠B, ∠C, ∠D respectively. … Therefore, the sum of the respective two adjacent angles of a parallelogram is equal to 180°. Hence, it is proved that the consecutive angles of a parallelogram are supplementary.
In a parallelogram, consecutive angles are supplementary (i.e. add to ) and opposite angles are congruent (i.e. equal).
Which are consecutive angles?
What are Consecutive Angles? A pair of angles formed on each side of the transversal when it interacts with two parallel lines are known as consecutive angles. The angles in the same region (either interior or exterior) on each of the parallel lines form consecutive angles pairs.

What type of parallelogram that consecutive angles are congruent?
A rectangle is a parallelogram, so its opposite angles are congruent and its consecutive angles are supplementary. Recall that the supplement of a right angle is another right angle.

What is a consecutive number?
Numbers that follow each other continuously in the order from smallest to largest are called consecutive numbers. For example: 1, 2, 3, 4, 5, 6, and so on are consecutive numbers.

Are the consecutive angles of a square complementary?
The diagonals bisect the angles of the square. Any pair of consecutive angles are supplementary. The diagonals are congruent. … Any pair of consecutive angles are supplementary.
What are the rules for a parallelogram?
- Opposite sides are congruent (AB = DC).
- Opposite angels are congruent (D = B).
- Consecutive angles are supplementary (A + D = 180°).
- If one angle is right, then all angles are right.
- The diagonals of a parallelogram bisect each other.
What is a consecutive side?
Consecutive sides are two sides that have an endpoint in common. … Sides AB and BC are examples of consecutive sides. Figure 2 There are four pairs of consecutive sides in this polygon. A diagonal of a polygon is any segment that joins two nonconsecutive vertices.
What is consecutive angles are congruent?
If a quadrilateral is a parallelogram, then consecutive angles are supplementary. If both pairs of opposite sides of a quadrilateral are congruent, then the quadrilateral is a parallelogram. If one pair of opposite sides of a quadrilateral are parallel and congruent, then the quadrilateral is a parallelogram.
What are consecutive vertices?
Consecutive vertices of a polygon are any two vertices that are connected by a single side.
What is the sum of consecutive angles?
The ‘consecutive interior angle theorem’ states that if a transversal intersects two parallel lines, each pair of consecutive interior angles is supplementary, that is, the sum of the consecutive interior angles is 180°.
What Consecutive angles are supplementary?
Consecutive Angles Are Supplementary
Supplementary angles are two angles that add up to 180-degrees. Let’s say that two of the consecutive angles have measurements of 35-degrees and 145-degrees. If we add these together (35 + 145), the sum is 180-degrees.
Is consecutive same as adjacent?
As adjectives the difference between consecutive and adjacent. is that consecutive is while adjacent is lying next to, close, or contiguous; neighboring; bordering on.
What are the consecutive composite numbers?
Since 90, 91, 92, 93, 94, 95, and 96 are seven consecutive numbers and all are composite. Thus, the two consecutive composite numbers before are 90, 91, 92, 93, 94, 95 and 96.
What are three consecutive composite numbers?
Example: Smallest 3 consecutive composites are clearly 8,9,10 but the formula gives us the numbers 26,27,28 and even 14,15,16 would be smaller.
What is consecutive sequence?
Consecutive number sequences are sequences constructed by concatenating numbers of a given type. Many of these sequences were considered by Smarandache and so are sometimes known as Smarandache sequences.
What is the parallelogram side theorem?
DEFINITION: A parallelogram is a quadrilateral with both pairs of opposite sides parallel. THEOREM: If a quadrilateral has 2 sets of opposite sides congruent, then it is a parallelogram. THEOREM: If a quadrilateral has 2 sets of opposite angles congruent, then it is a parallelogram.
Are consecutive angles in a parallelogram always congruent?
Consecutive angles of a parallelogram are congruent. Diagonals of a parallelogram bisect each other. The four angles of a rhombus are right angles. Consecutive sides of a rhombus are congruent.
Are consecutive angles of a rhombus complementary?
The consecutive angles of a rhombus are supplementary (add up to 180 degrees). The diagonals of a rhombus are perpendicular bisectors of each other (the diagonals form 4 right angles at their intersection, each diagonal divides the other into 2 congruent segments).
What is a parallelogram with four right angles?
Rectangle: A parallelogram with 4 right angles. Rhombus: A parallelogram with 4 sides with equal length.
How many angles does a parallelogram have?
You have learned that a parallelogram is a closed, plane figure with four sides. It is a quadrilateral with two pairs of parallel, congruent sides. Its four interior angles add to 360° and any two adjacent angles are supplementary, meaning they add to 180° . Opposite (non-adjacent) angles are congruent.
How many angles has a parallelogram have?
A parallelogram must have equivalent opposite interior angles. Additionally, the sum of all four interior angles must equal degrees. And, the adjacent interior angles must be supplementary angles (sum of degrees). Since, angles and are opposite interior angles, they must be equivalent.
Which of the following is correct in a parallelogram?
Adjacent angles are equal. Diagonals are equal. Adjacent angles are supplementary.
