Question

8. The sides of BC, CA and BA of a AABC are produced to X, Y and Z
respectively, as shown in the Figure. ZXCA = 120° and ZYAZ = 60°. Find
angles of the AABC. What type of triangle is AABC?​

Answer 1

Answer:

XCA=YAZ+ABC. (EXTERIOR ANGLE PROPERTY)

120=60+ABC

ABC=120-60

ABC=60

IT IS A EQUILATERAL TRIANGLE

Answer 2

Answer:

<BAC=60° <ABC=60° <ACB=60° IT'S AN EQUILATERAL ∆
