Question

Identify the triangles based on angles and name it. A) Acute triangle B) Right triangle C) Obtuse triangle D) Equilateral triangle

Answer 1

An acute triangle has all angles less than 90 degrees, a right triangle includes one 90 degree angle, an obtuse triangle has one angle over 90 degrees, and an equilateral triangle features all sides and angles as equal, with angles being 60 degrees.

Step-by-step explanation:

The question is about identifying different types of triangles based on their angles. Let's define each type:

A) Acute triangle: This is a triangle where all three angles are less than 90 degrees.
B) Right triangle: This is a triangle that has one angle exactly equal to 90 degrees. In terms of the sine, cosine, and tangent, the right angle is typically opposite the hypotenuse (the longest side) of the triangle.
C) Obtuse triangle: This type of triangle has one angle that is greater than 90 degrees.
D) Equilateral triangle: An equilateral triangle doesn't specify an angle but is a triangle where all three sides are of equal length. However, because all sides are equal, all angles in an equilateral triangle are 60 degrees.
