Name a pair of supplementary angles.
a. angle a e b and angle c e d
b. angle a e b and angle b e d
c. angle a e c and angle b e d
d. angle b e a and angle c e b

B.angle AEB and angle BED.

Step-by-step explanation:

We are given that a diagram .

We have to find a pair of supplementary angles.

Supplementary angles:The pair of angles whose sum is 180 degrees is called supplementary angles.

From given diagram

Hence, option B is true.

B.angle AEB and angle BED.

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.
