guys answer me fast ...​

Answer 1

Step-by-step explanation:

The angles that are opposite of each other are also congruent. To find out if your quadrilateral is a parallelogram, you could get out your protractor and measure each angle. The angles opposite of each other will have the same measurement.

Answer 2

Answer:

Theorem 8.4: In a parallelogram, opposite angles are equal Given: A parallelogram ABCD with AC as its diagonal To prove: ∠ A = ∠ C & ∠ B = ∠ D Proof: Opposite sides of parallelogram is parallel So, AB ∥ DC and AD‖∥ BC Adding (1) and (2) ∠BAC + ∠DAC = ∠DCA + ∠ BCA ∠BAD = ∠DCB Similarly, we can prove ∠ADC = ∠ABC Hence ...
