ABC is an issiscles triangle in which altitudes
BE and CT are drawn to equal side AC and AB
respectively Show that these
altitudes an equal
Answers
Step-by-step explanation:
Here we use ASA congruenceASA(angle side angle):Two Triangles are congruent if two angles and the included side of One triangle are equal to two angles & the included side of the other triangle.
Given:
ΔABC is an isosceles∆ with AB = AC, BD and CT are altitudes.
To prove:
BD = CT
Proof:
In ΔATC and ΔADB
∠A = ∠A. (Common)
∠ATC = ∠ADB (each 90°)
AB = AC (Given)
Therefore, ΔAEC ≅ ΔADB[by AAS congruence rule]
Thus, BD = CT (by CPCT)
Hence , altitudes BD & CT are equal.

Given:
ΔABC is an isosceles∆ with AB = AC, BD and CE are altitudes.
To prove:
BD = CE
Proof:
In ΔAEC and ΔADB
∠A = ∠A. (Common)
∠AEC = ∠ADB (each 90°)
AB = AC (Given)
Therefore, ΔAEC ≅ ΔADB[by AAS congruence rule]
Thus, BD = CE (by CPCT)
Hence , altitudes BD & CE are equal.
