Pythagorean Theorem And Classifying A Triangle By Sides

Let a, b and c be the sides of the triangle. If a 2 b 2 gt c 2, the triangle is acute triangle. If a 2 b 2 c 2, the triangle is right triangle. If a 2 b 2 lt c 2, the triangle is obtuse triangle. Where a and b are the lengths of the two shorter sides and c be the length of the longest side.

NOTE All of the lengths in the above problem represent the lengths of the sides of a triangle. Recall the Triangle Inequality Theorem from geometry which states The length of a side in a triangle is less than the sum of the other two sides. For example, 4, 7 and 13 cannot be the sides of a triangle because 924792 is not greater than 13.

You can classify a triangle by its sides by calling it an isosceles triangle, a scalene triangle, or an equilateral triangle. You can classify a triangle by its angles by calling it an equiangular triangle, a right triangle, an acute triangle, or an obtuse triangle. The angle classification always goes before the side classification. Rules

The Pythagorean Theorem, also referred to as the 'Pythagoras theorem,' is arguably the most famous formula in mathematics that defines the relationships Classify a triangle whose side lengths are given as11 in, 13 in, and 17 in. Solution a 2 b 2 11 2 13 2 121 169 290 c 2 17 2 289 Compare 289 lt 290. Hence, c 2 lt a 2 b

Now whenever sides meet in a triangle, they actually form angles. So the way we indicate this is by using a little curved arc symbol over here and we express that angle in terms of degrees. So wherever you have two sides of a triangle meet, they form angles, and there are 3 other types of triangles that we can classify based on those angles

9.1 The Pythagorean Theorem 457 Classifying Triangles The Converse of the Pythagorean Theorem is used to determine whether a triangle is a right triangle. You can use the theorem below to determine whether a triangle is acute or obtuse. EXAMPLE 5 Classifying Triangles Determine whether segments with lengths of 4.3 feet, 5.2 feet, and 6.1 feet

5-7 The Pythagorean Theorem Example 4A Classifying Triangles Tell if the measures can be the side lengths of a triangle. If so, classify the triangle as acute, obtuse, or right. 5, 7, 10 Step 1 Determine if the measures form a triangle. By the Triangle Inequality Theorem, 5, 7, and 10 can be the side lengths of a triangle.

Classifying Triangles by Using the Pythagorean Theorem We can use the Pythagorean Theorem to help determine if a triangle is a right triangle , if it is acute, or if it is obtuse. To help you visualize this, think of an equilateral triangle with sides of length 5 .
