True or false questions.

a figure cannot have both line symmetry and rotational symmetry.

true
false

when looking for rotational symmetry, do not consider a full turn of the figure.

true
false

if a figure can be divided into two equal parts, then the figure has line symmetry.

true
false

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

d 600 because 15*10*2=300

300+300=600
