What is the difference between an angle and a triangle?

A triangle is made up of 3 angles, which equal 180 degrees.


What is The measurement of an exterior angle of a triangle is equal to the sum of?

Interior angle+exterior angle = 180 degrees


A triangle has one angle of 80 degrees and another of 60 degreesHow many degrees must there be in the third angle?

Because the sum of the interior angles of a triangle must equal 180 degrees, the third angle must equal 180-80-60 = 40 degrees.


What is the angle of a triangle with 3 equal sides?

A triangle where all three sides are equal is called an equilateral triangle. The sum of all three angles in any triangle is 180 degrees, and since equal sides means equal angles, three equal angles totaling 180 degrees; each angle must be 60 degrees.


How many degrees does a right angle triangle add up to?

All triangles have a total of 180 degrees.The internal angles of any triangle add up to 180 degrees.Therefore, a RIGHT triangle's angle's added together equal 180 degrees.The Right Angle = 90 degrees + the other 2 angles total 90 degrees, making the total number of degrees in a Right Angle Triangle = 180 degrees.


Two angles in a triangle measure 48.3 degrees and 33.6 degrees. What is the measure of the third angle in the triangle?

The angles in a triangle will always equal 180 degrees. 180 - 48.3 - 33.6 = 98.1


What is the measure of the third angle of the triangle?

The third angle of a triangle is equal to 180 degrees minus (the sum of the first two angles).


How you can be sure that a triangle is 90 degrees?

All triangles have a total of 180 degrees.The internal angles of any triangle add up to 180 degrees.Therefore, a RIGHT triangle's angle's added together equal 180 degrees.The Right Angle = 90 degrees + the other 2 angles total 90 degrees, making the total number of degrees in a Right Angle Triangle = 180 degrees.


What is the name of the triangle that has an angle of 60 degrees and an angle of 70 degrees?

The third angle is 180-(60+70) = (180 - 130) = 50degrees.-- All of its angles aren't equal, so it's not an equilateral triangle.-- No two of its angles are equal, so it's not an isosceles triangle.-- No angle in it is 90 degrees, so it's not a right triangle.-- No angle in it is greater than 90 degrees, so it's not an obtuse triangle.--> It's an acute, scalene triangle.


Interior angles of a triangle are 50 degrees and 60 degrees. What is the third angle?

The sum of the three internal angles of a triangle is equal to 180 degrees. Since the two known angles are 50 degrees and 60 degrees, the third angle is equal to 180 - 50 - 60 = 70 degrees.


How many degrees does a right triangle equal?

The 3 interior angles of a right angle triangle add up to 180 degrees


What is a measure of each angle of an equilateral triangle?

all triangles equal 180 degrees so 180/3 equals 60 so, the measure of each angle of an equilateral triangle is 60 degrees.
