Answer:
- sides: isosceles
- angles: right
Step-by-step explanation:
At first, lets find the distance from one point to the other.
The same way, you can find that:
Since the triangle has only its two sides equal to each other (AB = AC),
it's an isosceles one.
As long as the angles are concerned, we gotta "cheat". In other words, we see that:
By the inverse of pythagorean theorem, we know that if the above equation holds, then we have a right-angled triangle. That is to say that,
A = 90
Since its an isosceles triangle, AB = AC,
B = C = (180 - A)/2 = 45 degrees
