Question

24. ABC is an Isosceles triangle with
AB = AC. D is a point on BC, such that
AD IBC
Prove that _BAD = ZCAD​

Answer 1

Answer:

two sides are equal

Step-by-step explanation:

draw construction A between make it D

Answer 2

Step-by-step explanation:

Given: ABC is an isosceles triangle with AB=AC and AD is perpendicular to BC

To prove: Angle BAD = Angle CAD

Proof: In triangle BAD and triangle CAD,

Angle ABD = Angle ACD [ Angles opposite to equal sides are equal ]

AD = AD [ Common ]

AB = AC [ Given ]

Triangle BAD is congruent to triangle CAD

Angle BAD = Angle CAD [ Corresponding sides of congruent triangles ]

NOTE: I couldn't use symbols of perpendicular, congruency etc, so I wrote them like that; in exam u need to write them using their symbols only.
