You get 130 because the formula for a triangle is A=bh/2. you multiply 20 and 13 then divide it by 2 and get your answer
Angle 4 is 34° this is becuase angle 2 and 4 are called vertical angles so they are the same. if you are doing proofs this is called VAAC (Vertical angles are congruent)
Answer:
∠A ≅ ∠D, ∠B ≅ ∠E, ∠c ≅ ∠F, AB = DE, BC = EF, AC = DF
Step-by-step explanation:
Given that triangles ABC and DEF are congruent. Now we need to choose correct congruency statements from the given choices.
We know that corresponding angles of congruent triangles are equal so we can write:
∠A ≅ ∠D
∠B ≅ ∠E
∠c ≅ ∠F
We know that corresponding sides of congruent triangles are equal so we can write:
AB = DE
BC = EF
AC = DF
comparing these with given choices we see that, First choice is correct.
0.7=7/10
0.8=8/10
0.75=3/4 this is between 0.7 and 0.8
