When a triangle has two congruent sides it is called an isosceles triangle. The angles opposite to the two sides of the same length are congruent. A triangle without any congruent sides or angles is called a scalene triangle. When two triangles are congruent it means that they have the same size and shape. please make me brainliest
In parallelogram the opposite sides are equal. Therefore we have the equation:

In the parallelogram, the sum of measures of the angles at one side is 180°. Therefore we have the equation:

Answer:
c = a + b → c = 7 + 7 = 14
A. 14
Answer:
To find the Slope: Slope Formula: m = y2 −y1 x2 −x1. Given points: P (6,2) and S(3,1) will be our (x1,y1) and (x2,y2) respectively. Hence x1 = 6,y1 = 2,x2 = 3,y2 = 1. Slope(m) = 1 −2 3 −6. ⇒ −1 −3 = 1 3.
