How many angles greater than a right angle
WebAn angle whose measure is equal to 90° is called a right angle. A 180° angle is called a straight angle. Angles such as 270 degrees which are more than 180 but less than 360 degrees are called reflex angles. A 360° angle is … WebMar 27, 2024 · Therefore 390 ∘ is coterminal with 30 ∘. As you saw above with negative angles, this means that 390 ∘ has the same ordered pair as 30 ∘, and so it has the same trig values. For example, cos 390 ∘ = cos 30 ∘ = 3 2. Figure 2.3.9. 1. In general, if an angle whose measure is greater than. 360 ∘ has a reference angle of 30 ∘, 45 ∘ ...

WebAn acute triangle (or acute-angled triangle) is a triangle with three acute angles (less than 90°). An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles. Since a triangle's angles must sum to 180° in Euclidean geometry, no Euclidean triangle can have more than one obtuse angle.
