Triangle ABC is isosceles (AB=AC).
AD is the median.
Is it true that \( ∢\text{BAD}=∢\text{DAC} \)?
Look at the triangle below.
AD is the median and crossed the predominant angle.
Is triangle ABC isosceles?
ABC is an isosceles triangle.
AD is the median.
What is the size of angle ?
In an isosceles triangle, the median to the base is also the height to the base.
That is, side AD forms a 90° angle with side BC.
That is, two right triangles are created.
Therefore, angle ADC is equal to 90 degrees.
90
