WebVideo transcript. Match these angles with their measures. There should be one angle in each category. We have 30 degrees, 60 degrees, 90 degrees, and 180 degrees. So there's a few that are very easy to spot out. This angle right over here, it makes a complete line. So this is clearly 180 degrees. So this one's 180 degrees. WebThe so-called ambiguous case arises from the fact that an acute angle and an obtuse angle have the same sine. If we had to solve. sin x = ½, for example, we would have. x = 45° or x = 135°. (Topic 4, Example 1.) In the following example, we will see how this ambiguity could arise. In triangle ABC, angle A = 30°, side a = 1.5 cm, and side b ...

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.. … WebAn obtuse angle is an angle that measures more than 90 degrees and less than 180 degrees. It's not clear why these angles take that name, as the word 'obtuse' can be … WebAn obtuse triangle is a triangle in which one of the interior angles is greater than 90°. It has one of its vertex angles as obtuse and other angles as acute angles i.e. when one angle measures more than 90°, the sum of … frd1103wm
