What is the measure of ∠ B in the parallelogram ABCD If the measure of ∠ A 80 *?

of angle B. = 1/2×(180–80)° = 50°.

What are the angles of a parallelogram equal to?

Parallelograms have angles totalling 360 degrees, but also have matching pairs of angles at the ends of diagonals.

Is it possible to find all the angles of a parallelogram if one angle is given as 80 give reason?

Answer Expert Verified For a parallelogram ABCD, opposite angles are equal. So, the angles opposite to the given 80° angle will also be 80°. It is also known that the sum of angles of any quadrilateral = 360°.

What are the sides of a parallelogram?

A parallelogram is a two-dimensional shape. It has four sides, in which two pairs of sides are parallel. Also, the parallel sides are equal in length. If the length of the parallel sides is not equal in measurement, then the shape is not a parallelogram.

Do parallelograms add up to 180?

Therefore, the sum of any two adjacent angles of a parallelogram is equal to 180°. Hence, it is proved that any two adjacent or consecutive angles of a parallelogram are supplementary.

What is the value of Amb in a parallelogram?

In parallelogram ABCD; AB || DC and AD || BC. So, (angle MAB + angle ABM) = 90°. In triangle MAB; sum of three angles = 180°. So, angle AMB = 180° – {angle MAB + angle ABM} = 180° – 90° = 90°.

What is the angle A M B in ABCD?

In parallelogram ABCD, the bisector of angle A and angle B intersect at m angle A is equal to 80. What is the angle A M B? – Quora In parallelogram ABCD, the bisector of angle A and angle B intersect at m angle A is equal to 80.

Is abcabcd a parallelogram?

ABCD is a parallelogram. If angle A=80, what does angle B equal? – Quora Answer: A parallellogram looks something like this, with sides parallell to each other in pairs. Any parallellogram can be divided into 2 triangles, which means that the sum of angles equals 360^\\circ.

What is the measure of all the angles of abcabcd?

ABCD is a parallelogram with ∠A = 80°. The internal bisectors of ∠B and ∠C meet each other at O. Find the measure of the three angles of ΔBCO. We know that the opposite angles of a parallelogram are equal. Hence, the measure of all the three angles of a triangle BCO is 40°, 50° and 90°.
