Question

Both questions//Congruence

Answer 1

Answer:

first one: 53°

Second one: reflective property of congruence <-(I'm not sure on this one but it seems like it)

Step-by-step explanation:

First one:

The measure of every triangle is 180°

we have to find that missing angle

so 180-53-74=53°

If its harder to understand you can make angle E x and solve 180=x+53+74

For the second one:

The reflexive property of congruence states that any geometric figure is congruent to itself.

This means that even same line segments and be congruent because of this property.

I hope this helped
