Calculating sides of a right triangle
How many equal sides does a right triangle have?
A right angle triangle can have only two equal sides. It is never possible to have all the 3 sides equal. According to Pythagorean Theorem - “In any right angled triangle the square of the hypotenuse ( the side opposite to the right angle) is always equal to the sum of squares of the sides that meet at the right angle.
How do you find the side lengths of a right triangle?
The length of the hypotenuse of a right triangle can be found using the Pythagorean theorem, which states that the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides.
What is the formula for determining sides of a triangle?
How to find the sides of a right triangle if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root: a = √ (c² - ... if leg b is unknown, then b = √ (c² - a²) for hypotenuse c missing, the formula is c = √ (a² + b²)
What are the lengths of the sides in a right triangle?
If all three sides of a right triangle have lengths that are integers, it is known as a Pythagorean triangle. In a triangle of this type, the lengths of the three sides are collectively known as a Pythagorean triple. Examples include: 3, 4, 5; 5, 12, 13; 8, 15, 17, etc.

We now have 2 side lengths of a right triangle, and using the Pythagorean Theorem can calculate the third, which is the height. Calculating the Angles Using the same right triangle we formed above, we can calculate the measure of the angle formed by the intersection of the slanted and long parallel sides easily using a trigonometric function.

2.3 Solving the right triangle The term ”solving the triangle” means that if we start with a right triangle and know any two sides, we can find, or ’solve for’, the unknown side. This involves a simple re-arrangement of the Pythagoras Theorem formula to put the unknown on the left side of the equation.

This diagram shows a right triangle—a triangle with one of its three angles measuring exactly 90o. Sides a and b form the 90o angle. The other two angles, identified as θ 1 and θ 2, are always less than 90o. Side c, the side opposite the 90o angle, is always the longest of the three sides. It is called the hypotenuse of the right triangle.
