It is an isosceles triangle having 2 equal angles of 30 degrees and an apex angle of 120 degrees
You need the measures of two sides and for the triangle to be a right triangle to figure out the third side.
No because the sum of the 2 smaller sides of a triangle must be greater than its longest side in order to construct a triangle.
A protractor is used for measuring angles and the 3 angles in a triangle add up to 180 degrees.
-- If one of the triangles' angle measures is 90 degrees, than it is a right triangle. -- If two of the triangle's angles add up to 90 degrees, then it's a right triangle. -- If the squares of the lengths of two sides add up to the square of the length of the third side, then it's a right triangle.
An acute angled scalene triangle.
60 degrees.
It is an isosceles triangle having 2 equal angles of 30 degrees and an apex angle of 120 degrees
The 3rd angle is 30 degrees and so it is an obtuse or a scalene triangle with 3 different side lengths and no right angle.
If two sides of a triangle are equal in length to the third side, then the triangle is equilateral, and all angles are 60 degrees.
You need the measures of two sides and for the triangle to be a right triangle to figure out the third side.
An isosceles triangle has two sides with equal measures. The third side can be any length.
It is either a triangle on a curved surface or a polygon with 4 or more sides.
No because the sum of the 2 smaller sides of a triangle must be greater than its longest side in order to construct a triangle.
A protractor is used for measuring angles and the 3 angles in a triangle add up to 180 degrees.
Not always, but it is possible. An obtuse triangle has 1 angle which measures greater than 90 degrees. A scalene triangle has all different lengths in size. It is possible for a triangle to have different angles, with one above 90 degrees, and have all different side lengths.
