So, multiples of 2π add or subtract from it to compute its coterminal angles. Now, subtract 2π from the angle. Hence, the coterminal angle of π/4 is equal to −7π/4. In such a triangle, the legs are equal in length (as a hypotenuse always must be the longest of the right triangle sides): a=b a = b. One leg is a base, and the other is the height – there is a right angle between them. So the area of an isosceles right triangle is: \text {area}=\frac {a^2} {2} area = 2a2.The Reference Angle Calculator is an invaluable tool for effortlessly finding reference angles without the need for manual calculations.
