The three internal angles of the triangle are denoted by ∠a, ∠b and ∠c.Follow these steps to use the calculator and find the value of the missing angle:Step 1: Enter the values of ∠a and ∠b in the calculator in whole numbers or in decimals. Step 2: Click on "Calculate" to...
Complementary angles in a right triangle Take a look at a right triangle's height – did you notice that altitude, h꜀, from the right angle to the hypotenuse creates two similar triangles? The adjacent complementary angles also have the same measures as the angles in the original right tri...
Note, in an equilateral triangle, all three interior angles are identical to one another, and all three side lengths are equal to one another. Thus, the vertex angle of an equilateral triangle is equal to 60°, as are the base angles. Try our equilateral triangle calculator. A right ...

If you're using your calculator, and you know the cosine of an angle, press the cos-1key to find the angle. The same applies to sine and tangent. References Math Is Fun: Sine, Cosine and Tangent Varsity Tutors: Basic Geometry – How to Find an Angle in a Right Triangle ...
An angle is formed when two rays are joined at their endpoints. Angles are usually measured in degrees. Learn all types of Angles in Geometry with interesting concepts, solved examples, interactive worksheets & solutions with Cuemath
Rule 2:Sides of Triangle--Triangle Inequality Theorem: This theorem states that the sum of the lengths of any 2 sides of a triangle must be greater than the third side.) Rule 3:Relationship between measurement of the sides and angles in a triangle: The largest interior angle and side are...
Remember, the sum of the angles of a triangle is 180 degrees. Just take what you are given in a problem and try to determine what will make the final angle add up to 180 degrees. A lesson provided by Mr. Feliz Try the "Triangle Calculator" below:...
linear pair pair of adjacent angles whose measures add up to form a straight angle is known as a linear pair. the angles in a linear pair are supplementary. \(\begin{array}{l}\text{consider the following figure in which a ray } \overrightarrow{op} \text{ stand on the line segment ...
