You can also use our triangle calculator to calculate perimeter using interior angles if all of the sides are not known. Circle Perimeter Formula P = 2πr r = radius Try our circumference calculator to solve using the radius, diameter, or area. Ellipse Perimeter Formula P≈π[3(a +...
A square is a quadrilateral (a shape we met in our quadrilateral area calculator) with four equal sides and four equal angles (right angles = 90°90°). It's one of the most basic shapes. It's a special case of a rhombus, a kite, a trapezoid, a parallelogram, and a rectangle, so...

A triangle is a three-sided polygon. Instructors often ask intermediate and advanced-level math students to calculate the missing angle in a triangle. One method of finding a missing angle is based on the premise that the sum of the interior angles of a
True or False: If two corresponding angles of two triangles are proportional, then the two triangles are similar. Without using a calculator find the exact values of arctan sqrt 3, arccos (sqrt 3)/2, and sin^-1 (sqrt 2)/ 2.
A trigonometric formula that uses two sides of the triangle and the adjacent angle, along with the sine function on your calculator, can determine the area of that triangle when the height is unknown. This lesson details how to apply...
This is because all of the lengths of its sides are equal as well as all of its vertices are right angles. With this, we can describe the square as a rectangle wherein all of the sides have equal lengths. Answer and Explanation...
