The triangles sum says that the 3 angle in a triangle always equal 180?
The three angles of a triangle are always equal to 180°, if not equal to 180° then it is not a triangle.
A triangle with an angle whose measures is greater than 90?
180 > x > 90: obtuse 180: straight 360 > x > 180: reflex
Two angle in a triangle equal 120 What is the measure of the third angle?
All angles in a triangle must equal 180, therefore 180 - 120 = 60
Angles whose sum is 180?
that's a straight angle 180 degrees, or that's a triangle...get it right
What is a triangle with an angle whose measure is greater than 90 And less than 180?
An obtuse triangle
What is The measurement of an exterior angle of a triangle is equal to the sum of?
Interior angle+exterior angle = 180 degrees
What is the difference between an angle and a triangle?
A triangle is made up of 3 angles, which equal 180 degrees.
Why is it impossible for a triangle to contain a 180 angle?
It is impossible to have a 180 degree angle because all three of a triangle's angles have to equal 180. If you have one angle of 180, then you would have 2 angles of 0, making a plain old straight line.
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).
The equal angles of an isosceles triangle?
To find the equal angels, base angles, of an isosceles triangle and you know the vertex angle, 180-vertex angle and then divide by two.
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.
What if a triangle has one angle equal to 180 degrees?
It would be a straight line.
