Triangle abc has vertices at a(3 , 7), b(5, 7), and c(3, 1). which statement proves that triangle abc is a right triangle?

There are no answer selections, but line x=3 is perpendicular from line y=7, so a right angle is formed as shown in the graph below.

Step-by-step explanation:

Step-by-step explanation:

AB is a horizontal line, and AC is a vertical line.

The intersection of AB and AC is a right angle; therefore, triangle ABC is a right triangle.

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.
