11. The triangles that are classified by angles are: acute, right, and obtuse.
To classify a triangle by angles, you can use the following guidelines:
- Acute Triangle: All three angles in the triangle are less than 90 degrees.
- Right Triangle: One angle in the triangle is exactly 90 degrees (a right angle).
- Obtuse Triangle: One angle in the triangle is greater than 90 degrees.
So, from the given options, the correct classification would be: acute, right, obtuse.
12. The triangles classified by side length and angle measurement are: scalene, acute and scalene, right.
To classify a triangle by side length and angle measurement, you can use the following guidelines:
- Scalene Triangle: All three sides of the triangle have different lengths.
- Isosceles Triangle: At least two sides of the triangle have the same length.
- Equilateral Triangle: All three sides of the triangle have the same length.
- Acute Triangle: All three angles in the triangle are less than 90 degrees.
- Right Triangle: One angle in the triangle is exactly 90 degrees.
- Obtuse Triangle: One angle in the triangle is greater than 90 degrees.
So, from the given options, the correct classifications would be: scalene, acute and scalene, right.
13. The quadrilaterals that have four equal sides are: square and rhombus.
A square is a quadrilateral with four equal sides and four right angles. In a square, all sides have the same length, and all angles are equal to 90 degrees.
A rhombus is a quadrilateral with four equal sides. However, unlike a square, a rhombus does not have right angles. Instead, its opposite angles are equal.
So, from the given options, the correct answer is: rhombus, square.
