False. You can have total internal reflection where the effective angle is greater than 90 deg

How does the angle of refraction compare to the angle of incidence measured from the normal when going from air to water?
Angle of refraction will be less compared to the angle of incidence in this case.
Is the angle of incidence is greater than the angle of refraction when light passes from a less dense to denser medium?
If you meant optical density by the term 'denser ' Then the answer is.... The light bends towards normal when it travels from a optically less dense medium to optically dense medium. So angle of incidence is greater than the angle of refraction
Which angle is less than 90 degree?
An acute angle
What type of angle is 1 degree?
an acute angle, which is an angle less then 90
Why is this false two acute angles side by side form one obtuse angle?
The degree of an acute angle is just less then 90 ( because it would be a right angle if it was 90). So that means it could just be a 5 degree acute angle and a 10 degree acute angle so that would only add up to 15 degrees, obviously not making it an obtuse angle.

Angle of refraction will be less compared to the angle of incidence in this case.
Is it true an acute angle had a measure greater than 90 degree's and less than 180 degree's?
False because an acute angle is greater than 0 and less than 90 degrees
If angle of incidence equals critical angle what is angle of refraction?
If the angle of incidence equals the critical angle, the angle of refraction would be 90 degrees. This occurs when light travels from a denser medium to a less dense medium and undergoes total internal reflection.
When a beam of light passes at an oblique angle into a material of lower optical density the angle if incidence is what?
less than the angle of refraction.
When a beam of light of passes at an oblique angle into a material of lower optical desity?
less than the angle of refraction
What shape is a 5 degree angle?
A 5 degree angle is an acute angle because it is greater than 0 but less than 90 degrees.
An acute triangle is a triangle that has one 90 degree angle true or false?
False. That is a right (-angled) triangle. An acute triangle has all three angles less than 90o

What are the properties of a obtuse angle triangle?
more than a 90 degree angle but less than a 180 degree angle
