Questions & Step-by-Step Solutions

In triangle DEF, if angle D = 45 degrees and angle E = 45 degrees, what type of triangle is DEF? (2021)
  • Step 1: Identify the angles given in triangle DEF. We have angle D = 45 degrees and angle E = 45 degrees.
  • Step 2: Recall the definition of an isosceles triangle. An isosceles triangle has at least two equal angles.
  • Step 3: Since angle D and angle E are both 45 degrees, they are equal.
  • Step 4: Conclude that triangle DEF has at least two equal angles, which means it is an isosceles triangle.
  • Triangle Classification – Understanding the properties of triangles based on their angles and sides, specifically identifying isosceles triangles.
  • Angle Sum Property – Recognizing that the sum of angles in a triangle is always 180 degrees.
