An isosceles triangle has a height of 8 and base of 30. What are all three angles of this triangle?
The three angles of triangle are
An isosceles triangle is symmetric from the centre. If we cut it in half, we will have 2 identical right-triangles with perpendicular
To calculate the identical angles opposite to height, we can use trigonometric identities:
Third angle can be calculated by subtracting the measure of 2 identical angles from sum of all angles in a triangle i.e.
