Triangles, Planar, Transformations

What is a Ray?

• It can be thought of as half a line. It has a point on one end, and it extends infinitely in the other direction.

• It specifies only location; it has no length, width, or depth.

• It has only one dimension: length. It continues forever in 2 directions but it has no width at all.

• It is a portion of a Line lying strictly between 2 points. It has a finite length and no width.

What are Supplementary lines?

• Two angles that share the same vertex and have one side in common between them.

• A pair of angles that add up to 90.

• 2 angles that add up to 180.

• Angles are on the same side of the transversal but on the outsides of the 2 parallel lines.

What is the difference between a Prime and an Original shape?

• Original is the shape before transformation and prime is an angle on a line.

• Original is the shape after transformation and prime is a banana.

• Prime is a place in the coordinate plane. And original is the 3rd quadrant in the coordinate plane.

• Prime is the shape after transformation. Original is the shape before the transformation.

What is the Pythagorean Theorem? (There are multiple answers)

• With right triangles, people can calculate the hypotenuse (long side) using the length of the 2 smaller sides.

• All sides are the same length, and all angles are the same length.

• One of the angles is greater than 90 the longest side is opposite the largest angle.

• a^2 + b^2 = c^2
