Answer 1

Answer:

yes, the sum of the all six angles is 4 right angles

Step-by-step explanation:

here,the triangle is a equilateral

so here that the two triangles are congruent

the the angles of that two triangles are equal

let the angle A =x

the 4 right angles =4 ✖ 90=320

sum of all six angles =6x

6x=320

x=320÷6=60

therefore, the sum of all six angles is equal to the 4 right angles
