A landscaper is putting a border on each side of a triangular garden. She plots the vertices of the garden (- 2,3), (5,5) and on a coordinate grid. Which expression can be used to find the length of the side of the triangle represented by the vertices (5,5) and (7,-3) on the graph? O A V(5 - 7)° + (5- (-3))? O . (5+7) + (5+(-3)² O C 5+7 5+(-3) 2 O D 2 5-(-3) 5-7

Polygon with three sides, three angles, and three vertices. Based on the properties of each side, the types of triangles are scalene (triangle with three three different lengths and three different angles), isosceles (angle with two equal sides and two equal angles), and equilateral (three equal sides and three angles of 60°). The types of angles are acute (less than 90°); obtuse (greater than 90°); and right (90°).
