Answer:
Construct a square of side length 4 cm
Step-by-step explanation:
* Lets explain how to construct a square polygon with side length 4 cm
- Use your straightedge to draw a horizontal line
- Measure on the horizontal line a segment of 4 cm
- Label its endpoints by A and B (AB = 4 cm)
- Open your compass at a distance greater then half AB (3 cm)
- Put the pin of the compass at point B and draw an arc intersects AB
at point E and the horizontal line at point F
- Open the compass at a distance greater than the length of the side
of the square (6 cm) and put its pin on the point E and draw an arc
- Put the pin of the compass on the point F without changing the open
of the compass and draw another arc
- The two arcs intersect each other at point G
- Join BG and measure 4 cm from point B and label the end point of
the 4 cm by C
- Open your compass at a distance 4 cm and put the pin on point C
and draw an arc and put it on point A with the same distance 4 cm
and draw another arc, the two arc intersect each other at point D
∴ ABCD is a square of side length 4 cm

Answer:
y= 4x/5 - 1
Step-by-step explanation:
slope , m=
y= mx + b , let's take (5,3)
then 3= 4(5)/5 + b , b= 3-4 = -1
so y= 4x/5 - 1
In a right-triangle, if either of the other two angles are "half that measure", or half of 90°, that means 45°, then the last angle will also have to be a 45° one too, and the sides coming from the 90° angle, will be equal twins, and therefore they can only make up one type-length hypotenuse, and due to that, you can only make that one triangle. Check picture below.
