What do we call a triangle that has all three sides of equal length?
Correct Answer
A. Equilateral Triangle
Explanation
An equilateral triangle is a triangle that has all three sides of equal length. This means that each side of the triangle is the same length, and all three angles are also equal, measuring 60 degrees.

What do we call a triangle with no equal sides?
Correct Answer
D. Scalene Triangle
Explanation
A triangle with no equal sides is called a scalene triangle. In a scalene triangle, all three sides have different lengths. This is in contrast to an isosceles triangle, where two sides are equal, and an equilateral triangle, where all three sides are equal. A right triangle refers to a triangle that has one angle measuring 90 degrees. Therefore, the correct answer is scalene triangle.

What is the least common multiple of 10 and 25?
Correct Answer
D. 50
Explanation
The least common multiple (LCM) is the smallest number that is a multiple of both 10 and 25. To find the LCM, we can list the multiples of both numbers and find the smallest common multiple. The multiples of 10 are 10, 20, 30, 40, 50, ... and the multiples of 25 are 25, 50, 75, 100, ... The smallest common multiple of 10 and 25 is 50, so it is the least common multiple.
