How do you know if a triangle doesnt have enough info to prove its congruent

to prove that the triangle is congruent, it should have one of these properties:

side side side

angle angle side

side angle angle

side angle side

angle side angle

right angle   hypotenuse  side

2,600 divided by 80 = 32.5

step-by-step explanation:

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
