gizmo warm-up
in the investigating angle theorems gizmo, you can manipulate a
dynamic figure to explore the properties of different angles.
1. in the gizmo, select vertical angles from the conditions menu. you
should see two intersecting lines like the ones shown to the right.
a
name the two pairs of angles that do not share a side. (they are nonadjacent.)
and
and
both pairs are vertical angles
b. drag the points to resize the angles. what appears to always be true about the
measures of the vertical angles?
turn on show angle measures and continue to resize to check if this is always true.
2. select form a linear pair to view a linear pair of angles (adjacent angles whose non-

sum= when you add is how much the whole amount is

distance= when you use angles and it means how far it goes

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
