The distance from the school to the corner is 0.9 kilometers. Angles are measured in degrees or radians. 30 seconds . So, for example, BCD is congruent to ECD, and so their corresponding sides and corresponding angles will also be congruent. angles that have the same measure. True or False. Step-by-step explanation: For the first question, the angles are congruent (they are not complementary because they dont add p to 90 degrees, and they are not supplementary because they dont add up to 180 degrees so they must be congrunet) Are supplementary angles always linear pairs? Parallel lines m and n are cut by transversal l above, forming four pairs of congruent, corresponding angles: ∠1 ≅ ∠5, ∠2 ≅ ∠6, ∠3 ≅ 7, and ∠4 ≅ ∠8. Angles are congruent, m<2 = 122, the <58 and the angle below <2 are congruent, because <2 and the angle below it forms a linear pair, they are supplementary 9. The measure of angles A and B above are both 34° so angles A and B are congruent or ∠A≅∠B, where the symbol ≅ means congruent.
