Students were asked over to answer a question at school and to claim what is most important for them to succeed. The one which response stood out from the rest was practice. Successful people definitely not born successful; they become successful with hard work and commitment. This is how you can fulfill your goals. followed below are one of the answer and question example that you will possibly make use of to practice and supercharge your understanding and also give you insights that should guide you to maintain your study in school.
What triangle has 0 reflectional symmetries?
I think your question must be “What triangle has 3 reflectional symmetries?”. Because there are given only three options, and all of them satisfy some rules to have reflectional symmetries. There is none triangle that has 0 symmetry. Let’s discuss it in detail :-
Rule 1 : A reflection symmetry must be a reflection line that bisects a figure such that they get folded on each-other across the reflection line.
Rule 2 : A reflection symmetry must pass through any vertex of the figure, and the sides intersecting at this vertex must be congruent sides.
Rule 3 : An equilateral triangle has three reflection symmetries as all sides are congruent and it is uniform from each vertex. Similarly, an isosceles triangle has only one reflection symmetry as it has only one pair of congruent sides.
Given option A is an equilateral triangle, so it has 3 reflection symmetries.
Given option B is an isosceles Right triangle, so it would have only 1 reflection symmetry.
Given option C is an isosceles triangle, so it would have only 1 reflection symmetry.
It means option B and option C have same answer i.e. only 1 reflection symmetry. But option A has 3 reflection symmetries.
So question must be “What triangle has 3 reflectional symmetries?”. Therefore, option A would be correct in that case.
They will possibly hopefully assist the student take care of the question by make use of the questions and answer examples. Then will be able to carry out some sharing in a group discussion and also study with the classmate regarding the topic, so another student also experience some enlightenment and still keeps up the school learning.
