- Q11. What is the sum of interior angles in a triangle?180 degrees90 degrees360 degrees270 degrees30s
- Q22. What is the area of a triangle with a base of 8 units and a height of 5 units?12 square units40 square units20 square units10 square units30s
- Q33. What is the Pythagorean Theorem?The sum of all angles in a triangle is 180 degrees.The longest side of a triangle is called the hypotenuse.The area of a triangle is equal to half the product of its base and height.In a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.The ratio of the lengths of the sides in a right triangle is always the same.30s
- Q44. What is the relationship between the lengths of the sides in an equilateral triangle?The lengths of the sides can vary.All sides are equalThe length of one side is twice the length of the other two sides.The shortest side is equal to the difference between the other two sides.The longest side is equal to the sum of the other two sides.30s
- Q55. What is the sum of the lengths of any two sides of a triangle?It can vary depending on the triangleAlways smaller than the length of the third sideEqual to the length of the third sideNone of the aboveAlways greater than the length of the third side30s
- Q66. What is the measure of each interior angle in an equilateral triangle?45 degrees120 degrees60 degrees90 degrees30s
- Q77. What is the relationship between the lengths of the sides in an isosceles triangle?One side is equal to the sum of the other two sidesNo sides are equalAll sides are equalThe lengths of the sides can varyTwo sides are equal30s
- Q88. What is the relationship between the angles in a right triangle?One angle is always 90 degreesAll angles are acute anglesThe sum of angles is always greater than 90 degreesThe angles can varyAll angles are obtuse angles30s
- Q99. What is the longest side of a right triangle called?Adjacent sideBaseOpposite sideHeightHypotenuse30s
- Q1010. What is the formula to calculate the area of a triangle?Area = (base * height) * 2Area = (base + height) / 2Area = base * heightArea = (base * height) / 230s
- Q1111. What is an equilateral triangle?A triangle with three equal sidesA triangle with no equal sidesA triangle with one equal sideA triangle with three equal angles30s
- Q1212. What is a scalene triangle?A triangle with one equal sideA triangle with three equal sidesA triangle with three equal anglesA triangle with no equal sides30s
- Q1313. What is the name of a triangle with one angle measuring 90 degrees?Acute triangleEquilateral triangleRight triangleObtuse triangle30s
- Q1414. What is an isosceles triangle?A triangle with two equal sidesA triangle with no equal sidesA triangle with three equal sidesA triangle with three equal angles30s
- Q1515. What is the sum of the lengths of any two sides of a triangle?Less than the length of the third sideEqual to the length of the third sideHalf of the length of the third sideGreater than the length of the third side30s
