What is the area of a trapezoid abcd with bases ab and cd , if: m∠c=m∠d=60°, ab = bc = 8 cm

cm².

Step-by-step explanation:

Given information: Trapezoid ABCD with bases AB and CD, m∠C=m∠D=60°, AB = BC = 8 cm.

m∠C=m∠D=, two base angles are same. It means ABCD is an isosceles trapezoid.

Draw perpendiculars from A and B on side CD. Both triangles ADE and BCF are congruent.

In a right angled triangle,

In triangle ADE,

The value of DE is 4.

The height of the trapezoid is . The length of base DC is

The area of a trapezoid is

where, a and b are bases of the trapezoid.

Therefore the area of trapezoid ABCD is cm².

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !
