How many lines of symmetry are in a regular polygon?
seven
twice as many as the number of sides
half as many as the number of sides
the same number as the number of sides
Answer:
the same number as the number of sides
lines of symmetry are in a regular polygon is the same number as the number of sides.
the correct option is (D)
What is Line of symmetry?A line of symmetry is a line that cuts a shape exactly in half. This means that if you were to fold the shape along the line, both halves would match exactly.
The number of lines of symmetry in a regular polygon is equal to the number of sides.
For example,
It has four lines of symmetry and four sides. A regular pentagon has 5 sides and 5 lines of symmetry.
Hence, lines of symmetry in a regular polygon is equal to the number of sides.

Answer:
b = 42° and c = 180-42 = 138°
Answer:
b) 42°
c) 138°
Step-by-step explanation:
Get 42° by looking at its vertical partner(vertical angle). Get 138° by subtracting 42 from it. Subtract 42 from the sum of the entire angle, and get 180° degrees.

Answer:
60°
Step-by-step explanation:
Since this is an equilateral triangle all the angles and sides are the same.
180÷3=60°
All the angLes will be 60°, because in a triangle ball angles must add up to 180°.

[Help Please!] Find the value of x.
Answer:
x = 52
Step-by-step explanation:
The exterior angle is equal to the sum of the opposite interior angles of a triangle
x+72 = 34+90
x +72 =124
Subtract 72 from each side
x = 124-72
x =52
Answer:
x = 52 degrees
Step-by-step explanation:
Let's first focus on the angle x + 72. Immediately adjacent to x + 72 is angle RQS. These two angles are "straight" in that they lie immediately adjacent to one another and add up to 180 degrees. Then angle RQS can be expressed as
180 degrees - (x + 72 degrees), or 108 - x degrees.
The three interior angles of the triangle must add up to 180 degrees. Hence
108 - x degrees + 34 degrees + 90 degrees = 180 degrees, and so:
108 - x + 34 = 90
This yields x = 52 degrees.

Answer:
C
Step-by-step explanation:
First find the area of the entire figure.
L= 36
W = 20
Area = 36 * 20 = 720
Find the area of the left right triangle.
Height = 20
Base = 1/2 * 36 = 18
Just as an aside, let me be a little grumpy for a moment. You should never have to guess what a dimension is on a diagram. It's sloppy. However for this problem you have no choice. But you could think to complain to your teacher.
Area = 1/2 * base * height
Area = 1/2 * 18 * 20 = 180
Find the area of the bottom right triangle.
The height is 1/2 20 = 10
The base is 36
Area of the lower triangle = 1/2 * 36 * 10 = 180
Area of the shaded figure = 720 - 180 - 180 = 360
