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 has one line of symmetry. This line of symmetry runs vertically down from the apex (the top vertex) to the midpoint of the base, dividing the triangle into two mirror-image halves. The two equal sides are symmetrical with respect to this line, while the base is not symmetrical.

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.
