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); as equilateral (3 equal sides and 3 equal angles), isosceles (2 equal s...
To calculate the other angles, we need the sine, cosine and tangent. In fact, the sine, cosine and tangent of an acute angle can be defined by the ratio between sides in a right triangle. Just like every other triangle, a right triangle has three sides. One of them is the hypothenus...

Find Reference Angle The reference anglemust be<90∘must be<90∘. Inradian measure, the reference anglemust be<π2must be<π2. Basically, any angle on the x-y plane has a reference angle, which is always between 0 and 90 degrees. The reference angle is always thesmallestangle that ...
How to Find the Central Angles and Inscribed Angles of a Circle Step 1: Determine if the vertex of the angle in question lies at the center of the circle or on the circle. This will determine if the angle is central or inscribed. Step 2: Identify the measurement of the arc of t...
Scale factor in geometry Scale is used in geometry to make accurate reproductions of figures; they are different sizes but not proportion. Figures are similar but to scale. Scale factor is used on similar geometric figures. You can find the scale factor of corresponding angles, sides, and even...
So quadrant 4 will have angles ranging from 270 to 330 degrees (see figure 10). Using the Unit Circle in Practice 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. ...
Denominator: In a fraction, the denominator is the number below (or after) the line. In the example above, 10 is the denominator of the fraction 3/10. How to Find a Fraction of a Number To work out a fraction of a number, all you need to do is divide that number by the fraction...
