Many math classes and standardized tests, such as the ACT and SAT, will require you to find a triangle's angles and sides. Triangles can be categorized as right (having a 90-degree angle) or oblique (non-right);
Calculating the sides of a triangle helps you to determine the perimeter of a triangle even if you only have the measure of two of the angles and one of the sides. To find the sides of the triangle, you need to use the Law of Sines. A scientific calculator with trigonometric functions ...

Trapezoids and triangles are two geometric shapes. A triangle is any three-sided figure. A trapezoid is a four-sided figure with one pair of parallel lines. You might want to calculate the area of a triangle or trapezoid if you had a room in that shape a
Remember, the unit circle can be used to find two unknown sides of a right triangle with a 30-degree angle and whose longest side, or hypotenuse, is a length of 7. Let's give it a try. Take note of where 30° is on the unit circle. Use that line and the x-axis to create a...
