Answer:
Option(B) is correct.
ΔHMG ≅ ΔKMJ ( by AA similarity criteria )
Step-by-step explanation:
Vertically opposite angle are two opposite angle formed when two lines cross each other.
Consider the two triangles ΔHMG and ΔJMK
∠MHG = ∠JKM = 47° (given)
also, ∠JMK = ∠HMG (vertically opposite angles)
Thus, ΔHMG ≅ ΔKMJ ( by AA similarity criteria )
AA similarity - if two angles of a triangles are equal to two triangle of another triangle then the two triangles are said to be similar.
Also note that if two angles of a triangle are equal then it is necessary that third angle is also equal.
Hence, Option(B) is correct.
Answer:
about 3
Step-by-step explanation:
i think ..........................
<1 = 123
60 + 63 = 123
180 - 123 = 57
180 n- 57 = 123
Triangle angle-sum theorem
Alternate exterior angles theorem (?)
Same side interior angles theorem
idk what the last one is about sorry
hope this helps
