Question

Part A: How many sides does a parallelogram have?

Part B: How are the opposite angles of parallelograms related?

Part C: If mA = 115° and m/B = 65°, determine m/C and m/D. Show your work.

Answer 1

A) A parallelogram has 4 sides.

B) The opposite angles of parallelogram are congruent.

C)
`\angle A \cong \angle C, \angle B \cong \angle D\\\\\implies m\angle C=115^(\circ), m\angle D=65^(\circ)`
