Alex drew two lines and two transversals. He wants to know the measures of angles 1, 2, and 3. Identify the measure of each angl
e and the relationship used to find the angle measure. 2 vertical parallel lines, M and N, intersected by 2 transversal lines P and Q. Lines P and Q intersect each other on line N. Between lines M and N, the 2 angles formed by lines M and P are labeled 1 and one hundred thirty-five degrees, and the smaller angle formed by lines M and Q is labeled 3. The non-adjacent angles formed by lines P and Q are labeled 2 and ninety-five degrees. m∠1= ° because ∠1 and the angle measuring 135° are Choose... angles. m∠2= 95 ° because ∠2 and the angle measuring 95° are Choose... angles. m∠3= ° because ∠1, ∠2, and ∠3 form a Choose... .
The mapping rule is another form used to express a quadratic function. The mapping rule defines the transformations that have occurred to the base quadratic function \begin{align*}y=x^2\end{align*}
