What is the largest angle in a triangle?

words check
The largest angle of a triangle is 5 times as big as the smallest angle. Is 120 five times as big as 24? Yes!

What is the largest possible angle in a triangle?

I think, your guess is wrong. You guess smallest possible angle is 1 and largest possible angle is 178 for triangle. Triangle with this angles have angles 1, 1, 178 as you know the sum of all angles of a triangle is 180.

How do you find the largest angle in a triangle?

use The Law of Cosines first to calculate the largest angle. then use The Law of Sines to find another angle. and finally use angles of a triangle add to 180° to find the last angle.

What is the name of the largest angle?

As the Angle Increases, the Name Changes:

Type of Angle Description
Right Angle is 90° exactly
Obtuse Angle is greater than 90° but less than 180°
Straight Angle is 180° exactly
Reflex Angle is greater than 180°

Which angle is the smallest in a triangle?

It’s because the angle, 57 degrees, is the smallest of the three angles.

Do all triangles equal 180 degrees?

The answer is yes! To mathematically prove that the angles of a triangle will always add up to 180 degrees, we need to establish some basic facts about angles. The first fact we need to review is the definition of a straight angle: A straight angle is just a straight line, which is where it gets its name.

What is the angle of a triangle?

The interior angles of a triangle always add up to 180° while the exterior angles of a triangle are equal to the sum of the two interior angles that are not adjacent to it. Another way to calculate the exterior angle of a triangle is to subtract the angle of the vertex of interest from 180°.

How do you find the angle of a triangle given two sides?


  1. Step 1 The two sides we know are Opposite (300) and Adjacent (400).
  2. Step 2 SOHCAHTOA tells us we must use Tangent.
  3. Step 3 Calculate Opposite/Adjacent = 300/400 = 0.75.
  4. Step 4 Find the angle from your calculator using tan-1

What are the 7 types of angles?

The 7 types of angles are: right angles, acute angles, obtuse angles, straight angles, reflex angles, full angles, and complementary angles.

What are the 5 types of angles?

Different Types of Angles

  • Zero Angles.
  • Acute Angles.
  • Right Angles.
  • Obtuse Angles.
  • Straight Angles.
  • Reflex Angles.
  • Complete Angle.

How do you know which angle is the smallest?

So, if given three side lengths, in order to put the angles in order from smallest to largest, first find the smallest angle by finding the angle opposite the smallest side, then, the medium-sized angle by finding the angle opposite the medium-sized side, and the largest angle opposite the largest side.

Which is the shortest side in right angle triangle?

In any triangle, the longest side is opposite the largest angle, and the shortest side is opposite the smallest angle. Thus, in a right triangle, the hypotenuse is always the longest side.

Which is the longest side of a 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.

What is the greatest number of obtuse angles a triangle can contain?

Johnson Z. A triangle can have a maximum of 1 obtuse angle.
