WebNov 1, 2014 · Finding Angles in a Right Triangle 1 Remember that every right triangle has one angle equal to 90 degrees. By definition, a right … WebThe five main types of angles are: Acute: An angle between 0 and 90 degrees. Right: A 90-degree angle. Obtuse: An angle between 90 and 180 degrees. Straight: A 180-degree angle or straight line. Reflex: An angle greater than 180 degrees but less than 360 degrees. Full: An angle that is 360 degrees. Parts of a Triangle WebOne way to do it is to make a system of equation: let a be the largest angle and b, c be the smaller two angles, and a + b + c = 180 a - 25 = c b + c = a + 30 Notice that b + c = 180 - a You can now rewrite the second equation by substituting b + c with 180 - a so that you only have to deal with 1 unknown term: 180 - a = a + 30 primare netzwerkplayer
