In the diagram, ABC is a triangle.
N is the point on AB such that ABC = AĈN.

(a)
Show that triangles ABC and ACN are similar.

The given 2 triangles are similar

Explanation:

Step 1 :

Given,

ABC is a triangle

N is the point on AB so that  ∠ABC = ∠ ACN

We need to show that the triangles ABC and ACN are similar

Step 2 :

Two triangles  are said to be similar if the corresponding angles are equal.

In the given triangles we have

∠A as the common angle

∠ABC = ∠ ACN

Since 2 angles of both the triangles are same, the third angle is also same, because the sum of the measures of all angles is 180 degrees

Hence the given 2 triangles are similar

the tides are influenced by both the moon and the sun, it's easy to see that when the sun lines up with the moon and the earth, as during a new moon or full moon, the tidal effect is increased. these are known as spring tides, named not for the season, but for the fact that the water "springs" higher than normal. on the other hand, if the sun and the moon are 90 degrees apart in relation to an observer on earth as during the first quarter moon or third quarter moon, then high tides are not as high as they normally would be. this is because despite its greater distance, the sun's mass allows it to exert enough gravitational force on the oceans that it can negate some of the effects of the moon's pull. this phenomenon of lower high tides is called a neap tide. if you need more information on this topic visit moonconnection.com.
