Which best explains whether a triangle with side lengths 5 cm, 13 cm, and 12 cm is a right triangle?

The correct answer is"the triangle is a right triangle because 205+144=169"

work shown below
given the side lengh 5cm,13cm,12cm,we can confirm it if it is a right triangle by applying the pythagrorean theorem.

13^2=5^2+12^2
169=25+144
169=169

so this confirms that it is a right triangle

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
