Question

Help me please and thank you

Answer 1

Since the triangles are the same, just flipped that means that all angles and segments are the same as well

I'm not sure if that's the "correct" way to prove it but that's why they're equal

Answer 2

Explanation:

In ΔEGF & ΔEGH,

EF ≅ EH {given}

FG ≅ HG { midpoint theorem}

EG ≅ EG {Reflexive property}

ΔEGF ≅ ΔEGH { S S S congruent }

∠1 ≅ ∠2 {Corresponding parts of congruent triangles are equal}
