(b)

Answer to Problem 38PPS
The given triangle is not equilateral.
Explanation of Solution
Given:
The vertices of the triangle is given as,
Calculation:
From the above part AB and BC sides are equal, but it is not equal to the side AC, hence all lengths are not equal.
No, the given triangle is not equilateral.
(c)
To find: The type of triangle formed.
(c)

Answer to Problem 38PPS

(d)
To find: The relationship between the triangles.
(d)

Answer to Problem 38PPS
The lengths of the sides of the triangle EFG are one half of the length of the sides of ABC triangle.
Explanation of Solution
Given:
The vertices of the triangle is given as,
Calculation:
The lengths of triangle ABC are given as,
