G Teaching triangles

A polygon is made of all line segments, closed with no gaps. The smallest possible number of sides is three and names a triangle. Triangles are named one of two ways by their sides or by their angles. According to their sides triangles can be either
all sides matching, equilateral at least two sides matching, isosceles or no sides matching, scalene
What is a triangle with no sides matching called? Classifying triangles by their sides one with
all sides matching is equilateral, at least two sides matching is isosceles, no sides matching is called scalene
What is a triangle with at least two sides matching called?
Classifying triangles by their sides one with
all sides matching is equilateral, at least two sides matching is isosceles, no sides matching is called scalene
What is a triangle with all sides matching called?
Classifying triangles by their angles, look at the largest angle. The largest angle names the triangle.
If the largest angle is less than 90 degrees, the triangle is called an acute triangle according to its angles. If the largest angle is 90 degrees, the triangle is called a right triangle according to its angles. If the largest angles is more than 90 degrees, the triangle is called an obtuse triangle. What is a triangle with a right angle called? a(n) triangle Classifying triangles by their angles, look at the largest angle. The largest angle names the triangle.
If the largest angle is less than 90 degrees, the triangle is called an acute triangle according to its angles. If the largest angle is 90 degrees, the triangle is called a right triangle according to its angles. If the largest angles is more than 90 degrees, the triangle is called an obtuse triangle. What is a triangle with all angles less than 90 degrees called? a(n) triangle Matching markings indicate congruent (matching) sides.
An ∟ indicates a right angle. Classifying triangles by their angles, look at the largest angle. The largest angles names the triangle.
If the largest angle is less than 90 degrees, the triangle is called an acute triangle according to its angles. If the largest angle is 90 degrees, the triangle is called a right triangle according to its angles. If the largest angles is more than 90 degrees, the triangle is called an obtuse triangle. What is a triangle with one angle more than 90 degrees called? a(n) triangle
