Answer:

Step-by-step explanation:

The area of a triangle is

A=bh/2 where b=base dimension and h=height

1) 10(12)/2=60mm^2

2) 14(34)/2=238in^2

3) 9.5(19.25)/2=91.4375yd^2

4) 4.9(23.7)/2=232.26m^2

5) 285=15b/2, 15b=578, b=38ft

6) 17h/2=18.7, 17h=37.4, h=2.2cm

7) 12.25b/2=128.625, 12.25b=257.25, b=21in

What triangle would be congruent to the original using a reflection over the x axis

Reflection in a Line
Topic Index | Geometry Index | Regents Exam Prep Center

A reflection over a line k (notation rk) is a transformation in which each point of the original figure (pre-image) has an image that is the same distance from the line of reflection as the original point but is on the opposite side of the line. Remember that a reflection is a flip. Under a reflection, the figure does not change size.


The line of reflection is the perpendicular bisector of the segment joining every point and its image.
A line reflection creates a figure that is congruent to the original figure and is called an isometry (a transformation that preserves length). Since naming (lettering) the figure in a reflection requires changing the order of the letters (such as from clockwise to counterclockwise), a reflection is more specifically called a non-direct or opposite isometry.
