Let us see some examples here to understand. Obtuse: an angle between 90 and 180-degrees. Their measures are equal, so m∠3 = 90. 1 decade ago. The longest edge of a right triangle, which is the edge opposite the right angle, is called the hypotenuse. It is not possible for a triangle to have more than one vertex with internal angle greater than or equal to 90°, or it would no longer be a triangle. How many grams in a cup of butternut squash? 90 degree angles are called right angles. Step 2: Place the centre of protractor at A and the zero edge along AB. How many somas can be fatal to a 90lb person? You can plot lines, line segments, rays and angles in a coordinate plane. This fact is to be expected because the angles are 180 degrees apart, and a straight angle measures 180 degrees. For example 90° means 90 degrees. Make a perpendicular line segment CD. These pairs are called vertical angles, and they always have the same measure. Who is the longest reigning WWE Champion of all time? One Degree. A straight line on the coordinate flat surface where all points on the line have the same y-coordinate. Make a line segment AB. The connecting point is the mid point O. A small angle might be around 30 degrees.Usually, when a finer measure is needed we just add decimal places to the degrees. Actually, it’s just a pinch. This angle is smaller than the right angle (which is equal to 90 degrees). 50 B. If you mean 70 degrees, that's a bit less than a right angle What is the WPS button on a wireless router? If the two angles of a triangle are 50 degree and 70 degree, then the measure of third angle is —————— A.
