No.
In the triangle ADB:
In the triangle ABC:
Then
In the same way,
Hello, thereddevils!
The diagram shows a right-angled triangle where angle BAC=90°.
A perpendicular is drawn from A to meet the hypothenus BC at D.
Prove that triangles ABC, ADB, and ADC are similar .Is angle BAD = angle DAC? . noCode:A * *|4 * *3| * * | * * | * * 1 | 2 * B * * * * * * * * * C D
In right triangle are complementary: .
In right triangle are complementary: .
. . Hence: .
So and have equal angles:
. .
Therefore: .
Similarly, prove that
