Math Example--Polygons--Triangle Classification: Example 7 |
Math Example--Polygons--Triangle Classification: Example 7TopicTriangles DescriptionThis example presents a triangle with two known angles, 20° and 50°, and an unknown angle x. Solving for x, we find it to be 110°. Since one angle is greater than 90°, the triangle is classified as obtuse. Triangles can be classified by their angles, where obtuse triangles have one angle over 90°. Reviewing examples like this aids students in understanding classification based on angle measures. Seeing multiple examples reinforces the rules and helps students apply classification consistently and accurately. |

Math Example--Polygons--Triangle Classification: Example 8 |
Math Example--Polygons--Triangle Classification: Example 8TopicTriangles DescriptionThis example shows a triangle with two angles, each measuring 60°. Since two angles are congruent, this triangle is classified as isosceles. Triangles can be categorized by side or angle properties. Isosceles triangles have two equal sides or two equal angles, as illustrated here. This collection of examples allows students to observe classifications and understand patterns in triangle properties. Examining multiple examples helps students confidently identify triangle types based on consistent characteristics. |

Math Example--Polygons--Triangle Classification: Example 9 |
Math Example--Polygons--Triangle Classification: Example 9TopicTriangles DescriptionThis example shows a triangle with two angles labeled x and one angle labeled y. Since two angles are congruent, the triangle is classified as isosceles. Triangles can be classified by side lengths or angle measures. Isosceles triangles, with two equal sides or angles, are common. Observing various examples helps students understand these classification criteria. Providing multiple examples allows students to identify patterns in side and angle relationships, reinforcing accurate triangle classification. |
