Yes. If it has a 90deg angle and 2 45 deg angles it will be.
Circle = Circumferance. Triangle = Perimeter. Perimeter for a Triangle, you count up the number of units on it.
Because the 3 interior angles of any triangle always add up to 180 degrees.

An isosceles triangle is a triangle that has two congruent or equal sides. For example, a triangle that has sides of 3,3, and 5.
Because the 3 interior angles of any triangle always add up to 180 degrees.
The formula to find the area of a dodecagon (12-sided polygon) is (apothem x perimeter)/2.
