How to Classify Triangles Based on Angles Measures
Problem 1 :
A triangle cannot have unequal side measures.
A) True B) False
Solution :
This is a false statement.
Because all three sides of the scalene triangle are unequal.
Problem 2 :
Name the triangle by observing its side lengths.
Solution :
By observing the figure,
AB = BC = AC = 5 cm
Since all the sides are equal in length, it is an Equilateral Triangle.
Problem 3 :
Identify the triangle based on indicated sides.
Solution :
By observing the figure,
AC and BC are congruent. It is represented by a single hash mark on each side.
So, it is an Isosceles Triangle.
Problem 4 :
Name the following triangles based on their sides and angles.
a)
Solution :
By observing the figure, <A = 90˚
Since one of the angles is 90˚, it is a Right Angle Triangle.
b)
Solution :
By observing the figure,
AB = BC = AC = 18 yd
Since all the sides are equal in length, it is an Equilateral Triangle.
c)
Solution :
By observing the figure, <A = 130˚
Since <A is greater than 130˚, it is an Obtuse Angle Triangle.
Problem 5 :
Identify the triangle based on the angles.
Solution :
By observing the figure, <B = 90˚
Since one of the angles is 90˚, it is a Right Angle Triangle.
Problem 6 :
Name the triangle by looking into its side measures.
Solution :
By observing the figure,
AB = 9 ft, BC = 4 ft, and, AC = 6 ft
Since all the sides are different in length, it is an Scalene Triangle.
Problem 7 :
A triangle having two sides of equal measures is known as _{----------- }triangle.
Solution :
A triangle having two sides of equal measures is known as Isosceles triangle.
Problem 8 :
The given triangle is :
A) Acute Triangle B) Obtuse Triangle C) Right Triangle
Solution :
By observing the figure,
Since one of the angles is greater than 90˚, it is an Obtuse Angle Triangle.
Problem 9 :
What is an Obtuse Angled Triangle ?
Solution :
If one of the angles is greater than 90˚, then the triangle is classified as an Obtuse Angle Triangle.
Problem 10 :
A triangle having all angles lesser than 90 degree is known as Right Angled Triangle.
A) Yes B) No
Solution :
No, It is a false Statement.
If all the angles of the triangle are all less than 90˚, then the triangle is classified as an Acute Angle Triangle.
