Questions: Use the figure to the right to (a) identify the triangle as scalene, isosceles, or equilateral and as (b) acute, obtuse, or right. The parallel markings (the two small parallel lines) on two or more sides indicate that the marked sides are of equal length. - Equilateral - Isosceles - Scalene (b) Is this triangle acute, obtuse, or right? - Right - Acute - Obtuse

Solution Steps

• The triangle has two sides marked with the same number of slashes, indicating that these sides are of equal length.
• A triangle with two equal sides is called an isosceles triangle.

• The image does not provide specific angle measurements, but based on the visual representation, the triangle does not appear to have a right angle (90 degrees) or an obtuse angle (greater than 90 degrees).
• Therefore, the triangle is likely an acute triangle, where all angles are less than 90 degrees.
