triangles. One way to show the relationships between types of triangles will be with a Venn diagram. A triangle is a polygon with three sides. There are many types of triangles. Each triangle can be classified by its angle types and its number of sides with equal lengths. Angles in a triangle can be acute, right or obtuse. When the sides of a

A triangle with a right angle (an angle that measures 90°) is a right triangle. The symbol indicates a right triangle. Obtuse Triangle If one angle of the triangle is greater than 90° (an obtuse angle), it is an obtuse triangle. Note: No triangle can have more than one obtuse or one right angle. 60 ° 70 ° 60 ° 130 ° 15 ° 35 ° 50 ° 60 ...

THE TRIANGLE AND ITS PROPERTIES 115 6.3 ALTITUDES OF A TRIANGLE Make a triangular shaped cardboard ABC. Place it upright on a table. How ‘tall’ is the triangle? The height is the distance from vertex A (in the Fig 6.4) to the base BC. From A to BC, you can think of many line segments (see the next Fig 6.5).

This lesson is designed to get students to recognize four types of triangles; isosceles, scalene, right and equilateral. Although identifying triangle types is not directly listed in the fifth grade geometry standards, students need a familiarity with angle types in order to set the background for classifying shapes based on their attributes and building a hierarchy of their properties.
