A ladder makes a 90° angle with a wall. The base of the ladder is 6 m away from the wall, and it reaches a height of 8 m. Find the length of the ladder.
Use the theorem: Hypotenuse² = Base² + Height².
In a right triangle, if one leg is 3 cm and the hypotenuse is 5 cm, find the other leg.
Rearrange the theorem to find the missing leg.
In a right-angled triangle, if one side is 9 cm and the other is 12 cm, what is the hypotenuse length?
Remember to apply the theorem.
True or False: The sides of a right triangle must always follow Pythagoras' Theorem.
Think about the definition of a right triangle.
A triangular garden has sides of 5 m, 12 m, and an unknown length. Verify if it's a right triangle using Pythagoras' Theorem.
Calculate the squares and apply the theorem.
If the height of a right triangle is tripled and the base stays the same, how does the length of the hypotenuse change?
Use the same base, but solve for new height to find new hypotenuse.
