I need help with this question

The first one is OBTUSE, since there is one obtuse angle(greater than 90 and less than 180)

The second one is acute, since all side have angles less than 90 degrees

The third and fourth ones are right triangles, the right triangle usually consists of one angle with 90 degrees(denoted by a square)

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.
