Answer:
SCALENE TRIANGLE
ACUTE TRIANGLE
Step-by-step explanation:
Types of triangles by side:
Equaliteral triangle: has three equal sides
Isosceles triangle: has two equals sides
Scalene triangle: has no equal sides
We have the sides:
23, 20 and 13 → different sides
SCALENE TRIANGLE
Types of triangles by angle:
Acute triangle: has tree angles with measure less than 90°
Right triangle: has one triangle 90°
Obtuse triangle: has one angle with measure greater than 90°
We have the angles:
62°, 72°, 46° → measure of all angles less than 90 °
ACUTE TRIANGLE
