To be a right angled triangle, it must follow the rule a² + b² = c² (where c is the longest side)

4.5² + 6² = 20.25 + 36 = 56.25
7² = 49
This is NOT a right angled triangle.

To make this into a right angled triangle, the longest side c should be longer. 
c = √56.25 = 7.5 inches

Can u help me
fiasKO [112]

The diagram shows that FG = IJ are congruent segments due to the double tickmarks. These are the hypotenuses of the right triangles.

So that takes care of the "H" in "HL".

The L stands for "leg", so we need to have a congruent pair of corresponding legs.

Due to the orientation of the triangles, it's not clear how the corresponding legs match up, but if any of the following is true

  • EF = IK
  • EF = JK
  • EG = IK
  • EG = JK

then we'd have enough to use HL.

\sqrt{64}=8\\\\8\dfrac17=8.14285714...\\\\8.\overline{14}=8.14141414...\\\\ \dfrac{15}2=7,5\\\\\\ \boxed{\ \dfrac{15}2\ \ \textless \ \ \sqrt{64}\ \ \textless \ \ 8.\overline{14}\ \ \textless \ \ 8\dfrac17\ }

5.

\sqrt{18}  doesn't belong with the other three because it is irrational number
The other three can be expressed as a ratio between two <span>integers.

-\dfrac{10}2=\dfrac{-10\ }2\\\\-13.4=-13\frac4{10}=\frac{-134}{\ 10}\\\\ 22.\overline7=22\frac79=\frac{205}9\\\\\\ \sqrt{18}=\sqrt{9\cdot2}=\sqrt9\cdot\sqrt2=3\sqrt2
