Answer:
1: "An equilateral triangle is never an obtuse triangle" & "An equilateral triangle is never an isosceles triangle."
2: Acute Isosceles Triangle
3: False! Option B.
4: D
Step-by-step explanation:
2: Isosceles Triangles have two equal sides. An acute triangle (or acute-angled triangle) is a triangle with three acute angles (less than 90°). An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles.
3: An equilateral triangle is a triangle in which all the sides and all the angles are equal.
4: In order for a triangle to be isosceles, it has to have two same sides. For a triangle to be equilateral, all sides and angles need to be the same. Refer to reasoning in Question 2 for next explanation.
