180 - 64.6 - 18.7 = 96.7 degrees
Any triangle that has an angle measuring 90 degrees is a right triangle.
acute-angled triangle
In a triangle, the sum of the measures of the angles is 180 degrees.
isocleles triangle
A triangle with the third angle that measures 30 degrees.This triangle is not isosceles nor equilateral but has one obtuse angle.
An obtuse triangle measures 162 degrees.
The third angle is 81 degrees because 180-41-58 = 81 degrees
Obtuse triangle
right triangle
Any triangle that has an angle measuring 90 degrees is a right triangle.
acute-angled triangle
A right angle triangle and the third angle measures 60 degrees
The 3 interior angles of an equilateral triangle each measures 60 degrees
-20 degrees Celsius.
The vertex angle of an isosceles triangle is equal to the measure of each of its base angles. Therefore, if one of the base angles measures 42 degrees, then the vertex angle also measures 42 degrees.
It is a right angle triangle and its 3rd angle is 70 degrees.
It is a right angle triangle providing that the 3rd angle is 30 degrees.
