a.
Answer to Problem 28WE
The given triangle is an isosceles triangle.
Explanation of Solution
Given information: The points are
Formula used:
Calculation: Since a triangle is an isosceles, only if two of its sides are equal to each other. And if square of one side of the triangle is equal to the sum of the length of other two sides then, the triangle said to be right angle triangle.
Hence, the given triangle is an isosceles triangle.
b.
To find: The type of triangle and its area.
