The pair of triangles that can be used to show that the slope of line a is same everywhere is upper half triangles
A triangle is a polygon with three vertices and three sides. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees
The total area that is bounded by a triangle's three sides is referred to as the triangle's area. In essence, it is equal to 1/2 of the height times the base, or A = 1/2 b h.
The pair of triangles in choice C (shown in the figure below) demonstrates that line a has a constant slope throughout.
Let's investigate:
Rise/run = slope
Regarding the initial lower triangle:
Rise = 3.5
Run = 4.5
Slope = 3.5/4.5 ≈ 0.8
For the upper second traingle:
Rise = 4
Run = 5
Slope = 4/5 = 0.8
As a result, it demonstrates that the graph's line's slope is constant throughout.
