It is a right angle triangle because it has a 90 degree angle and the 3 angles add up to 180 degrees.
False because the 3rd angle has to be a right angle of 90 degrees because the 3 angles of any triangle add up to 180 degrees.
A protractor is used for measuring angles and the 3 angles in a triangle add up to 180 degrees.
When the clock is at 3 o'clock, the hands form a right angle which measures 90 degrees.
An equilateral triangle, which has 3 angles of 60o.
There are typically 3 angles, obtuse, acute, and right. obtuse- an angle that measures over 90° acute- an angle that measures less than 90° right- an angle that measures exactly 90°
If measure angle 3 = x2 + 4x and measure angle 5 = 3x + 72, find the possible measures of angle 3 and angle 5
It is a right angle triangle because it has a 90 degree angle and the 3 angles add up to 180 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.
False because the 3rd angle has to be a right angle of 90 degrees because the 3 angles of any triangle add up to 180 degrees.
Let the second angle of the triangle be A. Then angle 1 = 2A : and angle 3 = 3A - 12 The internal angles of a triangle total 180° therefore :- 2A + A + (3A - 12) = 180 6A - 12 = 180 : 6A = 192 : A = 32 The angles measure 64° , 32° and 84° .
A protractor is used for measuring angles and the 3 angles in a triangle add up to 180 degrees.
When the clock is at 3 o'clock, the hands form a right angle which measures 90 degrees.
If you are dealing with an isosceles triangle, if one of the base angles measures 42 degrees then the other base angle measures 42 degrees. (By definitioin an isosceles triangle has at least 2 equal sides and the angle opposite those sides with be equal.) If you add up the degrees in each angle within a triangle, it will always equal 180 degrees. Knowing all this you can set up a formula: Angle 1 + Angle 2 + Angle 3 = 180 42 + 42 + Angle 3 = 180 Angle 3 = 96 degrees
Straight Angle.Did I help? :3
