Question

out of the four angles formed by two intersecting lines, one is 90 .prove that the three angles will be 90 each.​

Answer 1

Answer:

the intersection point where two lines intersecting makes angle of 90° will be perpendicular to each other. linA perpendicular to line B. as a result if one angle is of 90°. then other three will also be 90°.

Answer 2

Step-by-step explanation:

The intersection point where two lines intersecting makes angle of 90° will be perpendicular to each other.

line A perpendicular to line B.

as a result if one angle is of 90°. then other three will also be 90°.

A+B+C+D=360°

90° +90 +90° + 90° = 360°
