Maths

What is the coordinate of the point shown below?

The digram shows a right-angled triangle. Which of the statements is incorrect?

Work out the length of the hypotenuse of the triangle shown below.

Use Pythagoras’ Theorem to determine which of the sets of numbers below are Pythagorean triples:

Find the distance between the points (2, 1) and (4, 3).

Which side the the hypotenuse of the below triangle?

The digram shows a right-angled triangle. What is the length of the hypotenuse?

The right-angled triangle ABC has short sides of length 8 cm and 4 cm. Find the length of AC.

She did not identify the hypotenuse correctly.

She should have written 6 + 10 = x squared.

Sandra tried to calculate the unknown length. What mistake has she made in Step 1?

Made a mistake with re arranging the equation.

Mixed up the hypotenuse and shorter side lengths.

She doubled the sides instead of squaring.

Sandra tried to calculate the unknown length. What mistake has she made in Step 2?

Find the length of the perpendicular height using Pythagoras then multiply by 32.

Find the length of the perpendicular height using Pythagoras then multiply by 68

Find the length of the perpendicular height using Pythagoras, multiply by 32 then divide by 2.

What do you need to do in order to find the area of the triangle shown below.
