WebMar 17, 2024 · Since the angle chosen is one of the three possible choices which are equally likely, the probability of an obtuse angle in a triangle is 1/6. SCALENE TRIANGLES For Scalene triangles, we can apply a similar technique where we would have two intersecting circles of equal radius with their center lying of the circumference of the other circle. WebIn this activity, students digitally sort shapes by parallel or perpendicular lines or by acute, right, and obtuse angles. This supports their understanding of why shapes fall into those different categories. Based on standard 4.G.A.2, however this could be a good reinforcement/review activity for grades 5 or enrichment for grade 3 students.
WebA right triangle is a triangle where one of its angles is a right angle (i.e. 90°). The other two angles are acute angles. You may have noticed that the side opposite the right angle is always the triangle’s longest side. It is called … WebAn obtuse triangle has only one angle greater than 90° since the sum of the angles in any triangle is 180°. If one of the angles is greater than 90°, then the sum of the other two angles must be less than 90°, so the other two angles must both be acute angles. For DEF above, ∠D + ∠F = 60° < 90°, so ∠D and ∠F are acute angles.
