What Is A Unique Triangle – Chapter 8.3.3 How Many Different Acute Triangles Can You Draw? How many different right scalene triangles can you draw? Remember that triangles can be classified by the length of their sides and the measure of their angles. Sides: Scalene – no side is congruent isosceles – two sides are equilateral – all three sides are congruent angles: Acu – all three angles are acute Right – is a right angle Obtuse – an obtuse angle is congruent

The sum of the lengths of any two sides of a triangle is greater than the length of the third side. What does this mean? If you take the three sides of a triangle and add the two shortest sides, the sum will be greater than (not equal to) the third side. If this is not true, it is not possible to construct a triangle with the given side length.
Example 1: Determine whether a triangle with sides of length 5 cm, 8 cm and 12 cm can be formed? Are both sides shorter (>) than the longer side? Yes, it is possible to construct a triangle with sides of length 5 cm, 8 cm and 12 cm.
11 Example 2: Determine whether a triangle with sides of length 3 ft, 4 ft and 9 ft can be formed? Are both sides shorter (>) than the longer side? No, it is not possible to construct a triangle with sides of length 3 feet, 4 feet and 9 feet.

A triangle has three straight sides connecting it. The length of the sides can vary, but the length of the longest side cannot be equal to or greater than the sum of the other two sides. Also, a triangle has three interior angles and the sum of these three angles is always 180 degrees. This is true for all triangles, including the six types we see today.

Let’s start with the three types of triangles that are classified by the measure of their largest angle. These are acute, right and obtuse triangles.
But how do you know which is which? Look at the largest angle of each triangle and note whether the angle is greater than, less than, or equal to 90 degrees.
We can see that the largest angle in the triangle on the left is 70 degrees. 70 is less than 90, so it is an acute triangle. Just remember that acute angles are less than 90 degrees. It’s easy to remember, because “cute” things are often small, like puppies and kittens.
We can see that the largest angle in the middle triangle is 90 degrees. You may recall that a 90 degree angle is a right angle, so this triangle is a right angle.

Finally, in the right triangle, the largest angle is 117 degrees. Because it is greater than 90 degrees, it is an obtuse angle, so we call this triangle an obtuse triangle.
That’s all for these three kids! We simply find the largest angle and the name of the triangle corresponds to the name of that angle.
