Explanation:

First Sub - Question

To solve this, we recall the definitions of each triangle type:

• A right triangle has a 90° angle, not related to side congruence here.
• An isosceles triangle has at least two congruent sides.
• Adjacent angle is about angles, not a triangle type.
• An obtuse triangle has one obtuse angle, not about side congruence.
• A scalene triangle has no congruent sides.

We recall the definitions:

• A right triangle is defined as a triangle with one right (90°) angle.
• An obtuse triangle has one obtuse angle.
• An equilateral triangle has all sides equal.
• An equiangular triangle has all angles equal.
• An acute triangle has all angles acute.

Answer:

E. scalene triangle
