Degrees
it depends on the angle. Right angles always have 90 degrees. You can use a protractor to measure the angle
Use the fact that the sum of the three angles is 180 degrees.Use the fact that the sum of the three angles is 180 degrees.Use the fact that the sum of the three angles is 180 degrees.Use the fact that the sum of the three angles is 180 degrees.
It is an isosceles triangle having 3 interior angles 2 of which are equal in size and the 3 angles add up to 180 degrees. Use Pythagoras' theorem to find its altitude and then use trigonometry to find the sizes of its angles. The angles work out as 53 degrees, 53 degrees and 74 degrees
Finding degrees of angles, or for drawing circles.
He may want to form a corner of 90 degrees using complementary angles
For a pentagon, which has 5 sides, you can use the formula: Total Sum of Interior Angles = (5 - 2) * 180 degrees Total Sum of Interior Angles = 3 * 180 degrees Total Sum of Interior Angles = 540 degrees So, the total sum of the interior angles in a pentagon is 540 degrees.
No, angles smaller than 90 degrees are acute, angles bigger than 90 degrees are obtuse, angles that are 90 degrees exactly are right-angles, and angles larger than 180 degrees are reflex angles.
Angles that are less than 90 degrees are acute angles. Angles that are 90 degrees are right angles, and angles that are greater than 90 degrees are obtuse angles.
It is an "obtuse angle."Angles that are less than 90 degrees are "acute angles."Angles that are exactly 180 degrees are "straight angles."Angles that are exactly 90 degrees are "right angles."
Angles that add to 180 degrees are called supplementary angles, while angles that add to 90 degrees are called complentary angles.
