16. The number of lines of symmetry of a regular polygon is equal to the vertices of the polygon. * 1 point True False 17. An angle has two lines of symmetry. * 1 point True False 18. A regular pentagon has no lines of symmetry. * 1 point True False 19. Mirror reflection always leads to symmetry. * 1 point True False 20. Regular polygons have equal sides and equal angles. * 1 point True False giving out brainliest ​

i can't read the graph

step-by-step explanation:

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

hope it

lol we need to see what the question is asking about

step-by-step explanation:

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
