To decide: Whether each statement about triangles or quadrilaterals is true or false.
Given: ” All equilateral triangles are equiangular triangles. ”
The statement is correct.
All the angle in equilateral triangle is 600
In equiangular triangle also all the angles are 600
All the sides are also same.
All equilateral triangles are equiangular triangles.
Hence the statement cannot be false,
The statement is true
Parallel And Perpendicular Lines Exercise 2.5 Carnegie Learning 2nd Edition Answers Page 119 Problem 23 Answer
To decide: Whether each statement about triangles or quadrilaterals is true or false.
Given: ” An isosceles triangle can be an obtuse, acute, or right triangle. ”
The statement is false
An isosceles triangle is always acute.
In isosceles triangle two angles are same
Hence two angles are less than 900
Thereby all the angles are less than 900
Counterexample is

Only acute triangle satisfy this
The statement is false

To decide: Whether each statement about triangles or quadrilaterals is true or false.
Given: ” A scalene triangle can be an obtuse, acute, or right triangle”
The statement is true
A scalene triangle means all the lengths are different
In this case the triangle can be an obtuse, acute, or right triangle
A scalene triangle can be an obtuse, acute, or right triangle.
The statement cannot be false
The statement is true, a scalene triangle can be an obtuse, acute, or right triangle.
Page 119 Problem 25 Answer
To decide : Whether each statement about triangles or quadrilaterals is true or false.
Given : ” A right triangle can be an obtuse triangle.”
The statement is false
If one angle is right angle the sum of other two angle is 900
Hence the triangle cannot be obtuse.
The counter example is

Here one angle is 900,all other angles are less than 900
The statement is false a right triangle can’t be an obtuse triangle.
