Y = 10 units
Explanation:
The two triangles are similar due to Angle-Angle similarity theorem. So, the ratios of their sides are equal
y/14 = 15/(15 + 6)
y/14 = 15/21
y = 10 units
Answer:
Step-by-step explanation:
#3 slope is the change in y divided by the change in x
So -10-(-8)/13-15 = -2/-2=1
for #5 the slope is always the coefficient of x when written in slope intercept form so the slope is 3
#7 the gradient is infinite
Answer:
a) corresponding angles of similar polygons are congruent
b) corresponding sides of similar polygons are proportional
c) a triangle is a polygon
Step-by-step explanation:
By <em>definition</em>, similar polygons have congruent corresponding angles and proportional corresponding sides.
A triangle is a polygon, so two triangles will be similar if they have congruent corresponding angles and proportional corresponding sides.
___
For an n-sided polygon, one only needs to show the conditions are met for n-1 angles and sides. Those will determine the measures of the final angle/side.
