Question

Classify the triangle:

A triangle. One side has a single slash mark. One side has a double slash mark and the third has a triple slash mark. One angle measures one hundred thirty degrees.

acute isosceles

obtuse scalene

right scalene

obtuse isosceles

Answer 1

the slash marks are used to indicate that a side is the same length as (congruent with) another side which has the same marking.

You have three different markings: 1 slash, 2 slashes, and 3 slashes. That means that none of the sides are the same length as another side. You also know that one angle is \(130^\circ\). What sort of triangle fits those conditions?
