Questions & Step-by-Step Solutions
Which of the following is NOT a property of triangles?
Step 1: Understand what a triangle is. A triangle is a shape with three sides and three angles.
Step 2: Learn about the types of triangles based on their angles: acute triangles (all angles less than 90 degrees), right triangles (one angle exactly 90 degrees), and obtuse triangles (one angle greater than 90 degrees).
Step 3: Identify the property in question. The question asks which statement is NOT true about triangles.
Step 4: Recognize that not all triangles have all angles acute. For example, a right triangle has one angle that is 90 degrees, which is not acute.
Step 5: Conclude that the statement 'All triangles have all angles acute' is NOT a property of triangles.
