The four-sided geometric figure pictured is called a parallelogram. One feature of parallelograms is that opposite sides have equal lengths. A parallelogram is shown. It is folded from one point to another to form 2 triangles.

The dotted line splits the parallelogram into two triangles. What is true about the congruency of the two triangles?

More information is needed.
The triangles can be proven congruent using SSS.
The triangles can be proven congruent using HL.
The triangles are not congruent.

The triangles can be proven congruent using SSS.

Step-by-step explanation:

The four-sided geometric figure pictured is called a parallelogram. One feature of parallelograms is that opposite sides have equal lengths.

A parallelogram is shown. It is folded from one point to another to form 2 triangles.

The dotted line splits the parallelogram into two triangles. What is true about the congruency of the two triangles?

The triangles can be proven congruent using SSS.

The triangles can be proven congruent using HL.

The triangles are not congruent.

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
