a - сторона, протилежна стороні CD.

b - сторона, протилежна стороні AD.

c - сторона, протилежна стороні AB.

d - сторона, протилежна стороні BC

Answer 2

ABCD is a parallelogram. In a parallelogram, opposite sides are parallel and equal in length, and opposite angles are also equal. Let's break down the properties of a parallelogram and determine the values of a, b, c, and d.

Opposite sides in a parallelogram:

In a parallelogram, opposite sides are parallel and equal in length. Therefore, we can say that: - Side AB is parallel and equal in length to side CD. - Side AD is parallel and equal in length to side BC.

Opposite angles in a parallelogram:

In a parallelogram, opposite angles are equal. Therefore, we can say that: - Angle A is equal to angle C. - Angle B is equal to angle D.

Now, let's determine the values of a, b, c, and d.

Side lengths in a parallelogram:

Since opposite sides in a parallelogram are equal, we can label the side lengths as follows: - Side AB = a - Side BC = b - Side CD = a (equal to AB) - Side AD = b (equal to BC)

So, we have: - AB = a - BC = b - CD = a - AD = b

Angle measurements in a parallelogram:

Since opposite angles in a parallelogram are equal, we can label the angle measurements as follows: - Angle A = x - Angle B = y - Angle C = x (equal to A) - Angle D = y (equal to B)

So, we have: - Angle A = x - Angle B = y - Angle C = x - Angle D = y

To summarize: - Side lengths: AB = CD = a, BC = AD = b - Angle measurements: A = C = x, B = D = y
