Cameras

First photograph due to Niepce First on record shown - 1822 Basic abstraction is the pinhole camera lenses required to ensure image is not too dark various other abstractions can be applied. Cameras. Abstract camera model - box with a small hole in it. Pinhole cameras work in practice.

Parallel Lines and Proportional Parts

Parallel Lines and Proportional Parts. Section 7.4. Proportional parts of triangles. Non parallel transversals that intersect parallel lines can be extended to form similar triangles. So, the sides of the triangles are proportional. Side Splitter Theorem or Triangle Proportionality Theorem.

Applying Properties of Similar Triangles

Applying Properties of Similar Triangles. Students will be able to use properties of similar triangles to solve problems. 1. Triangle Proportionality Theorem. If a line parallel to a side of a triangle intersects the other two sides, then it divides those sides proportionally . If
