Question
- which statement is true about parallel lines? a. they are coplanar and intersect. b. they are not coplanar and intersect. c. they are coplanar and do not intersect. d. they are not coplanar and do not intersect. for items 2 - 5, lines $ell$ and $m$ are intersected by transversal $t$. $ellparallel m$ 2. select all the angles that are supplementary to $angle2$. a. $angle3$ c. $angle5$ e. $angle7$ b. $angle4$ d. $angle6$ f. $angle8$ 3. select all the angles that are congruent to $angle6$. a. $angle1$ c. $angle3$ e. $angle7$ b. $angle2$ d. $angle4$ f. $angle8$ 4. complete the following plan to prove that $angle4congangle8$. use the same - side interior angles postulate to show that $angle4$ is supplementary to $square$. show $angle8$ and $square$ are $square$ because they form a $square$. since $angle4$ and $angle8$ are $square$ to the same angle, they are congruent to each other. 5. if $mangle4 = 105$, what is $mangle5$? $mangle5=square$ 6. select all the true statements given the figure. a. $mangle4=mangle1 + mangle2 + mangle3$ b. $mangle4=mangle2 + mangle3$ c. $mangle4=mangle3$ d. $mangle4 = 180 - mangle1$ e. $mangle4=mangle1 + mangle2$ for items 7 - 9, use the figure shown. 7. what is $x$? a. 32 c. 118 b. 62 d. 242 8. what is $y$? $y=square$ 9. select all the true statements. a. $x = y$ b. $x + y=180$ c. $y = z$ d. $x + z=180$ e. $y + x=180$

Step1: Definición de líneas paralelas
Las líneas paralelas son coplanares (están en el mismo plano) y no se intersectan.
Step1: Ángulos suplementarios
Los ángulos suplementarios suman 180°. El ángulo 2 y el ángulo 4 forman un par de ángulos adyacentes en una recta, entonces son suplementarios. También, el ángulo 2 y el ángulo 6 son ángulos correspondientes y los ángulos 6 y 8 son adyacentes en una recta, por lo que el ángulo 2 y el ángulo 8 son suplementarios.
Step1: Ángulos congruentes
Los ángulos congruentes tienen la misma medida. El ángulo 6 y el ángulo 8 son ángulos verticales (congruentes), el ángulo 6 y el ángulo 2 son ángulos correspondientes (congruentes).
