Question

In tri ABC,AP perpendicular to BC,
BQ perpendicular to AC, B-P-C and A-Q-C,then
1) prove tri CPA ~ tri CQB.
2) write the proportionality of the corresponding sides of tri CPA and tri CQB.
3) If AP=7, BQ=8, BC=12, then find AC



​

Answer 1

Step-by-step explanation:

Given AP perpendicular BC, BQ perpendicular AC

To proove . . . 1st Triangles CPA ~triangle CQB

Proof. . . In triangle CPA and CQB

angle Q = Angle P ( 90⁰)

Angle C= Angle C (common)

Through AA criteria triangle CPA ~ CQB
