Refer to our Texas Go Math Grade 5 Answer Key Pdf to score good marks in the exams. Test yourself by practicing the problems from Texas Go Math Grade 5 Lesson 11.2 Answer Key Triangles.

Essential Question How can you classify triangles? Answer: Triangles can be classified either according to their sides or according to their angles. All of each may be of different or the same sizes; any two sides or angles may be of the same size; there may be one distinctive angle Now, According to the sides, the triangles are classified into: a. Equilateral triangle b. Isosceles triangle c. Scalene triangle According to the angles, the triangles are classified into: a. Acute triangle b. Right triangle c. Obtuse triangle

Classify triangles by the lengths of their sides.

Classify triangles by the measures of their angles.

The type of triangle outlined in the pattern can be classified by the length of its sides as an “Equivalent triangle”. The triangle can also be classified by the measures of its angles as an “Acute triangle”.

Math Talk Mathematical Processes Is an equilateral triangle also a regular polygon? Explain. Answer: In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°. It is also a regular polygon. So, it is also referred to as a regular triangle

Classify triangle ABC by the lengths of its sides and by the measures of its angles.

Step 1 Measure the sides of the triangle using a centimeter ruler. Label each side with its length. Classify the triangle by the lengths of its sides.

Triangle ABC is a “Scalene triangle”

• What type of triangle has 3 sides of different lengths? Answer: We know that, The triangle that has 3 different side lengths is: Scalene triangle Hence, from the above, We can conclude that The triangle that has 3 different side lengths is: Scalene triangle

• What is an angle called that is greater than 90° and less than 180°? Answer: We know that, The angle that is greater than 90° and less than 180° is: Obtuse angle Hence, from the above, We can conclude that The angle that is greater than 90° and less than 180° is: Obtuse angle

Try This! Draw the type of triangle described by the lengths of its sides and by the measures of its angles.

Math Talk Mathematical Processes Can you draw a triangle that is right equilateral? Explain. Answer: We already know that to be equilateral all the sides should be equal and all the corresponding angles also should be equal. So, it is not possible to draw a right-angled equilateral triangle

Classify each triangle. Write isosceles, scalene, or equilateral. Then write acute, obtuse, or right.

Problem Solving

Question 4. H.O.T. Can you tell that a triangle is obtuse, right, or acute without measuring the angles? Explain. Answer: To determine whether the triangle is acute, right, or obtuse, add the squares of the two smaller sides and compare the sum to the square of the largest side. If this sum is greater, the triangle is acute, and if this sum is smaller, the triangle is obtuse

Classify the triangles in the structures below. Write isosceles, scalene, or equilateral. Then write acute, obtuse, or right.

Circle the figure that does not belong. Explain.

Question 8. Parker drew a triangle with no congruent sides and a 95° angle. Classify the triangle by the lengths of its sides and measures of its angles. Explain. Answer: It is given that Parker drew a triangle with no congruent sides and a 95° angle Now, Since there are no congruent sides, the triangle is a “Scalene Triangle” Now, 95° is an angle that is greater than 90° and less than 180° and this angle is called an “Obtuse angle” Hence, from the above, We can conclude that The triangle is a “Scalene Triangle” since there are no congruent sides and is also called an “Obtuse Triangle” since one of the angles is 95°
