How many sides does an octagon have quizlet?

A hexagon has 6 sides and 6 angles . How many sides and angles does a octagon have? An octagon has 8 sides and 8 angles.

How many angles does a octagon have?

8 angles

An octagon contains six triangles or 1080 degrees. This means with 8 angles each angle is 135 degrees.

How many levels are there in octagon?

What shape that has 8 sides?


An octagon is a shape with 8 sides and 8 angles.

How many triangles make up an octagon?

Method 2: Dividing a Regular Octagon into 8 Triangles

Divide the octagon into 8 triangles. Each triangle has 2 sides of equal length.

How do you draw an octagon?

How do you measure an octagon?

All sides are the same length (congruent) and all interior angles are the same size (congruent). To find the measure of the angles we know that the sum of all the angles is 1080 degrees (from above)… And there are eight angles… So the measure of the interior angle of a regular octagon is 135 degrees.

How do you find the diameter of an octagon?

  1. d = s + 2x.
  2. s2 = x2 + x2 = 2x2
  3. x = s/√2.
  4. d = s + 2x = d = s + 2(s/√2) = s + √2 s = (1 + √2) s.
  5. d = (1 + √2) × 60 = 144.85 feet.
