select allthat apply.

which of the following are true of a regular pentagon?
each angle measure is 108°.
the angle sum is 720°.
it has six sides.
it is equilateral.

1. Sqaure 2. Equialteral Triangle 3. Each angle is 108°

Step-by-step explanation:

Before we go ahead with this problem let us see the sum of all internal angles in various polygons.

a) Triangle : 180

b) Quadrilateral : 360

c) Pentagon : 540

d) Hexagon : 720

Now let us do each part

Part 1.

Polygon  sum is 360° , hence it is a quadrilateral . And each angle measures 90° , Hence it is either a square or a rectangle . Hence our answer from options is square

Part 2,

Measure of each angle of polygon is 60°.

60°*3= 180°

60°*4=240°

60°*5=300°

None of the above gives you a polygon except first . Hence our answer is an triangle and as every angle is equal is an equilateral triangle.

Part 3,

A regular pentagon has sum of its all interior angles is 720°. Total nos. of angle is 5 . Hence measurement of each angle will be

Hence option b is right

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
