Answer:

AB = 3.16 units

Step-by-step explanation:

AB = root{(x2 - x1)^2 + (y2 - y1)^2}

AB = root{(6 - 3)^2 + (0 - (-1))^2}

AB = root{(3)^2 + (0 + 1)^2}

AB = root{9 + (1)^2}

AB = root{9 + 1}

AB = root 10

Therefore, AB = 3.16 units

What must be true of the side lengths in order to build a triangle with only two angles the same size?
ale4655 [162]

A triangle with two angles of the same size is an isosceles triangle. So two of its sides are going to have the same measure and the third different. The length of the sides will depend on the height of the measure of the given angles.

Step-by-step explanation:

Isosceles triangles can be classified into an isosceles right triangle, isosceles obtuse, isosceles acute depending on the measurements of its internal angles.
