What type of triangle has an angle of 120 degrees and two angles of 30 degrees?
An isosceles triangle
What is the measure of the interior angle of an equilateral triangle?
Each of the interior angles of an equilateral triangle is 120 degrees.
A triangle has a 30 degrees angle and a right angle What is the measure of the third angle?
Angle A + Angle B + Angle C = 180 degrees. 30+90+C=180 120+C=180 C=60 degrees.
A triangle has two equal sides and one angle that is 120 degrees What are the other two angles?
30 degrees each
A triangle has angles 120 degrees 40 degrees and 20 degrees What is this type of triangle?
Scalene
Which triangle does have one internal angle of 120 degrees?
An obtuse angled triangle can have can have one internal angle of 120 degrees.
Can a scalene triangle have an angle of 30 degrees and an angle of 120 degrees?
Yes it can.
What is the angle of rotation for an equilateral triangle?
60 degrees, 120 degrees
What is the third angle on a triangle if you have 60 degrees and 60 degrees?
The last angle would have to be 60 degrees as well. Since there are 180 degrees in a triangle, 60+60=120 and 180-120=60, it has to be 60 degrees.
What type of triangle has an angle of 120 degrees and two angles of 30 degrees?
An isosceles triangle
What is the measure of an exterior angle of an equilateral triangle?
120 degrees.
What is the measure of the third angle of a triangle if one angle measures 120 degrees and the other measures 35 degrees?
180-120-35 = 25 degrees
What triangle measures 120 degrees on the top and 30 degrees on the side?
It is an isosceles triangle having 2 equal angles of 30 degrees and an apex angle of 120 degrees
If a triangle has an angle that is 120 degrees and two others that are 30 degrees is it a right angle?
no because none of the angles are 90 degrees
Show how to construct a 120 degree angle?
draw a base and use this to draw an equilateral triangle each angle of an equilateral triangle adds up to 60 degrees. To have an angle of 120 degree use this angle and then draw another side of a triangle next to it to get a 120 degree angle.
How many degrees are there in each exterior angle of an equilateral triangle?
120 degrees. Each interior angle of an equilateral triangle is 60 degrees, so each exterior angle is 180 - 60 = 120 degrees It can also be worked out by the formula Exterior angle of a polygon = 360/no. of sides of the polygon = 360/3 = 120Each exterior angle measures 120 degrees and each interior angle measures 60 degrees because there are 180 degrees on a straight line.
What type of triangle has an angle that measures 120 degrees and an angle that measures thirty degrees?
An isosceles triangle, because the angles of a triangle add up to 180 and you already know that one angle measures 120 degrees, the other is 30, and so the unknown angle must also be 30 degrees. Since two of the angles are the same, two of the sides are going to be the same, making it an isosceles triangle.
