Now Elena is trying to draw a triangle with side lengths 4 cm, 3 cm, and 8 cm. She uses her ruler to draw a 4 cm line segment AB. She uses her compass to draw a circle around point B with radius 3 cm. She draws another circle, around point A with radius 8 cm. Explain what Elena’s drawing means

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius

: )

answer: b

step-by-step explanation:

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.
