## What is the angle of a right triangle?

90 degreesRight Triangle A right angle has a value of 90 degrees (90∘ ).

A right triangle is a triangle in which one angle is a right angle.

The relation between the sides and angles of a right triangle is the basis for trigonometry..

## What are the 3 angles of a right triangle?

Since the three interior angles of a triangle add up to 180 degrees, in a right triangle, since one angle is always 90 degrees, the other two must always add up to 90 degrees (they are complementary). The side opposite the right angle is called the hypotenuse. The sides adjacent to the right angle are the legs.

## What is the measure of one acute angle in a right triangle?

In a right angled triangle, one angle will be 90o . Since we know the measure of one of the other acute (less than 90o ) angles, we subtract the sum of the two known angles from 180 to calculate the measure of the other acute angle.

## Does 4 5 6 make right triangles?

Explanation: For a set of three numbers to be pythagorean, the square of the largest number should be equal to sum of the squares of other two. Hence 4 , 5 and 6 are not pythagorean triple.

## How do you solve for acute angle?

Divide the length of side “a” by the length of the hypotenuse, side “c.” This is the sine of the acute angle that shares the horizontal leg with the right angle. Enter this ratio into your scientific calculator and use the inverse sine function to determine the angle.

## Does 9 12 and 15 make a right triangle?

Explanation: By virtue of the Pythagorean Theorem, in a right triangle the sum of the squares of the smaller two sides equals the square of the largest side. Only 9, 12, and 15 fit this rule.

## Which Triangle is a 30 60 90 Triangle?

A 30-60-90 triangle is a right triangle with angle measures of 30º, 60º, and 90º (the right angle).

## What are the rules for a right triangle?

The Pythagorean theorem states that: In any right triangle, the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares whose sides are the two legs (the two sides that meet at a right angle).

## Do isosceles triangles have two equal angles?

An isosceles triangle therefore has both two equal sides and two equal angles. The name derives from the Greek iso (same) and skelos (leg). A triangle with all sides equal is called an equilateral triangle, and a triangle with no sides equal is called a scalene triangle.

## Does 6 8 and 10 make a right triangle?

2 Answers. They are equal, and thus, the triangle is a right triangle. … These sides are 6: 8: 10, then the triangle is a right one.
