Given: ab is the perpendicular bisector of ik. name two lengths that are equal

The two lengths that are equal are IB and KB

Explanation:

Given

Line AB (Bisector)

Line IK

When a line is bisected, it means the line is divided into two equal parts.

Given that line AB bisects line IK.

Let's assume the bisection was done at point B, the two lengths that are equal are given as follows.

Line IK = Length IB + Length KB

Since, it's a bisection IB = KB.

So, we have

IK = IB + IB

IK = 2IB

IB = ½IK

IB = KB = ½IK

Hence, the lengths are;

Length IB and Length KB

- "the civil rights movements"

- "following the american civil war and abolition of slavery, the united states entered a period known as reconstruction, during which black americans continued to suffer from disenfranchisement, racial segregation, and economic oppression. beginning in the early 1950's, black americans launched a series of major campaigns of civil resistance, emphasizing the need for nonviolent protests and civil disobedience."

"such as the montgomery bus boycott of 1955-56, a campaign launched by rosa parks against the policy of racial segregation of the public transit system in alabama. “sit-ins” became popular across the american south, particularly in greensboro, north carolina, increase national sentiment."

- "the counterculture movement"

- "counterculture began to develop in the united states following the rise of conformity in american culture during the 1950s. by 1963, youth, particularly those of the white middle class, began rejecting the cultural standards and normality of their parents, opting for progressive attitudes instead. the movement gained momentum as the civil rights movement became increasingly successful and as the u.s. military intervention of vietnam began to take a negative turn."

"hippie counterculture moved further into popular culture following the summer of love in 1967 when thousands of people came together in the haight-ashbury neighborhood of san francisco. along with greenwich village in new york city, haight-ashbury became a hub for the counterculture movement."
