Bellwork Know and Do in the planner Bellwork in your notebook Draw an acute triangle, an obtuse triangle, and a right triangle in your notebook. Bellwork Know and Do in the planner Bellwork in your notebook Write an example of supplementary angles. Objectives •I know how to describe properties of isosceles, equilateral, and scalene triangle. •I can classify triangles by angles and sides. Warming up Draw a triangle with at least two equal sides. Label the length of each side. Draw a triangle with no equal sides. Label the length of each side. Warming up Draw a triangle with at least two equal sides that has an obtuse angle. Label the length of each side. Draw a triangle with no equal sides. Label the length of each side. What is equilateral triangle? 3 equal sides 3 equal angles, always 60 degrees Is this an equilateral triangle? Yes, equal sides and angles What is isosceles triangle? 2 equal sides 2 equal angles Is this an isosceles triangle? Yes (at least) two equal sides & angles What is scalene triangle? No equal sides No equal angles Is this a scalene triangle? Yes, no equal sides/angles What are the possible names of the following triangle? What are the possible names of the following triangle? By angle By side Is it an acute Equilateral? triangle? Is it an obtuse triangle? Is it a right triangle? Isosceles? Scalene? It is an obtuse isosceles triangle. By angle By side Is it an acute Equilateral? triangle? Is it an obtuse triangle? Is it a right triangle? Isosceles? Scalene? What are the possible names of the following triangle? What are the possible names of the following triangle? By angle By side Is it an acute Equilateral? triangle? Is it an obtuse triangle? Is it a right triangle? Isosceles? Scalene? It is a right scalene triangle. By angle By side Is it an acute Equilateral? triangle? Is it an obtuse triangle? Is it a right triangle? Isosceles? Scalene? How are you doing so far? Copy the following table in your notebook and complete it with triangles that represent both attributes.
