## Can a triangle have one obtuse and right angle?

A triangle cannot have one obtuse and one right angle as 90o+ angle >90o= angle >180o..

## What is a true triangle?

A triangle has three sides, three vertices, and three angles. The sum of the three interior angles of a triangle is always 180°. The sum of the length of two sides of a triangle is always greater than the length of the third side.

## Do all triangles have right angles?

A right triangle may be isosceles or scalene. In an obtuse triangle, one angle is greater than a right angle—it is more than 90 degrees. … In an acute triangle, all angles are less than right angles—each one is less than 90 degrees. An acute triangle may be equilateral, isosceles, or scalene.

## Is it possible to have a right obtuse triangle?

A right triangle cannot be obtuse because of the sizes of the angles therein.

## Can a triangle have both an acute and right angle?

Question 945360: A triangle cannot have both an acute angle and a right angle? In a right triangle, BOTH of the other angles MUST be acute. An obtuse angle (greater than 90 degrees) would make the sum of the angles greater than 180 degrees, which is impossible.

## How do you know if three numbers make a right triangle?

If the sum of the lengths of the two shorter sides is greater that the length of the third side, then you can form a triangle (the istri assignment), otherwise it is impossible to form any triangle from them. Then determine if it is a right triangle, using the Pythagorean Theorem.

## How do you solve a2 b2 c2?

Introduction: Pythagorean Theorem The formula is A2 + B2 = C2, this is as simple as one leg of a triangle squared plus another leg of a triangle squared equals the hypotenuse squared.

## Can a triangle have 3 right angles?

No, real, triangle can have three right angles. … The sum of the angles formed must equal 180° and the sum of the length of two sides must be greater than the length of the third. A right angle takes up half of the 180°, so the remaining 90° must be split between the other two angles.

## Which shape has most right angles?

RectangleThe Rectangle A rectangle is a four-sided shape where every angle is a right angle (90°). Also opposite sides are parallel and of equal length.

## 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.

## What are the rules for a right triangle?

The longest side of a right triangle is called the hypotenuse, and it is the side that is opposite the 90 degree angle. If the length of the hypotenuse is labeled c , and the lengths of the other sides are labeled a and b , the Pythagorean Theorem states that a2+b2=c2 a 2 + b 2 = c 2 .

## What is a right angle triangle called?

Right Isosceles Triangle Has a right angle (90°), and also two equal angles.

## How do you figure out if a triangle is a right triangle?

A right triangle is a triangle in which one of the angles is a 90∘ angle. The “square” at the vertex of the angle indicates that it is 90 degrees. A triangle can be determined to be a right triangle if the side lengths are known. If the lengths satisfy the Pythagorean Theorem (a2+b2=c2) then it is a right triangle.

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

In a right triangle, the hypotenuse is the longest side, an “opposite” side is the one across from a given angle, and an “adjacent” side is next to a given angle. We use special words to describe the sides of right triangles.

## What are the types of right triangles?

There are three types of special right triangles, 30-60-90 triangles, 45-45-90 triangles, and Pythagorean triple triangles.

## Why can a triangle only have one right angle?

The right triangle has one 90 degree angle and two acute (< 90 degree) angles. Since the sum of the angles of a triangle is always 180 degrees... The two sides of the triangle that are by the right angle are called the legs... and the side opposite of the right angle is called the hypotenuse.

## Does 4 5 6 make right triangles?

The three numbers 4, 5, 6 make a Pythagorean Triple (they could be the sides of a right triangle).
