The triangle in the right side of the first row, the triangle in the left side of the second row and the triangle in the left side of the third row are labeled correctly.
<h3>What triangles are represented correctly?</h3>
Triangles can be defined in terms of their base and their height. Both are linear measures. The base is one side of the triangle and the height is a line perpendicular to the base that meets the vertex opposite to the base.
Based on this explanation we find that the triangle on the right of the first row, the triangle on the left of the second row and the triangle on the left of the third row are labelled correctly.

Answer:
m=60º
n=30º
Step-by-step explanation:
a triangle is 180º total
an equilateral triangle has all 60º angles
since the one symbol for a right angle is cut between two triangles you can say that the one angle in the equilateral triangle +n=90º
substituting the values 60+n=90
so n=30
Then since a triangle is 180º you can make an equation that says 180=90+m+n
again substituting 180=90+m+30
60=m
an easy way to check is 180=90+30+60 180=180
