What is a parallelogram?

Back

A parallelogram is a four-sided figure (quadrilateral) with opposite sides that are parallel and equal in length.

Front

What is the sum of the interior angles of a parallelogram?

Back

The sum of the interior angles of a parallelogram is 360 degrees.

Front

What is the measure of opposite angles in a parallelogram?

Back

In a parallelogram, opposite angles are equal in measure.

Front

If one angle of a parallelogram is 65 degrees, what is the measure of the opposite angle?

Back

The opposite angle is also 65 degrees.

Front

What is an isosceles triangle?

Back

An isosceles triangle is a triangle that has at least two sides of equal length, which also means that the angles opposite those sides are equal.

Front

What is the sum of the interior angles of a triangle?

Back

The sum of the interior angles of a triangle is always 180 degrees.

Front

If two angles of an isosceles triangle are 58 degrees, what is the measure of the third angle?

Back

The third angle measures 64 degrees (180 - 58 - 58 = 64).

Front

In an isosceles triangle, if one angle is 71 degrees, what are the measures of the other two angles?

Back

The other two angles are both 54.5 degrees (since 180 - 71 = 109, and 109/2 = 54.5).

Front

What is the relationship between adjacent angles in a parallelogram?

Back

Adjacent angles in a parallelogram are supplementary, meaning they add up to 180 degrees.

Front

If angle B of parallelogram ABCD is 65 degrees, what is the measure of angle D?

Back

Angle D measures 115 degrees (180 - 65 = 115).
