Grade 4 Geometry is a 10-question AI-hosted trivia round about grade 4 geometry, voiced by Sofia and playable in about 5 minutes with no signup.
The round rewards depth of knowledge over quick guesses and the difficulty stays balanced for mixed audiences.
Part of the Math Trivia Games cluster
Don't let the "Grade 4 Geometry" playtime fool you. 10 questions sounds short, but at medium difficulty the pack is designed to separate casual fans from people who actually know grade 4 geometry.
Rules are tight: 10 questions, 20-second timers, instant reveal. Expect the whole pack to wrap in about 5 minutes. Sofia brings the on-mic energy — sofia makes every fact feel like a discovery — bright, enthusiastic, genuinely curious.
Questions draw from Basic geometric shapes, Types of angles, Line relationships, Symmetry concepts, Quadrilateral properties, and Triangle classifications. Nothing is published verbatim on this page — that would defeat the point — but those themes are the target surface area.
Hit a good score? Share the link — every challenge carries your score through to the next player so they know exactly what they're chasing. Pack is published in English.
Expect roughly 5 minutes for a full playthrough. "Grade 4 Geometry" has 10 questions on a 20-second-per-question clock, with voice-hosted reveals in between.
Players don't need to register. Share the link, they open it, they play. Trivana is built so hosts (classrooms, events, Discord servers) can spin up a game without forcing every participant through a signup flow.
"Grade 4 Geometry" is hosted by Sofia, one of Trivana's seven AI gameshow hosts. Sofia narrates every question, reacts to answers in real time, and gives the pack its on-mic personality. You can read Sofia's full profile and hear the voice at /hosts/sofia.
The pack is rated medium — a mid-level challenge — expect questions that reward genuine familiarity with the topic but don't require deep expertise. Combined with the serious tone, it's a good fit for mixed groups with some knowledge of the topic.
At its core, "Grade 4 Geometry" is about grade 4 geometry. Questions pull from themes including Basic geometric shapes, Types of angles, Line relationships, Symmetry concepts, Quadrilateral properties, and Triangle classifications. Exact questions are held back from the landing page so the first run still feels fresh.
Published language: English. Trivana supports ten languages end-to-end (English, Spanish, Hindi, French, German, Portuguese, Japanese, Arabic, Korean, Chinese), and the AI host speaks each of them natively rather than translating text on top of an English recording.
Fact-check status: passed

Answer: C. Right angle
Explanation: A right angle measures exactly 90 degrees and is often represented by a small square symbol at the corner where the two lines meet.
Answer: C. Parallel lines
Explanation: Parallel lines are lines that stay the same distance apart and will never cross or touch, no matter how far they are extended.
Answer: B. Acute angle
Explanation: An acute angle is any angle that is smaller than a right angle, meaning its measurement is strictly less than 90 degrees.
Answer: D. Square
Explanation: A square is a specific type of quadrilateral that must have all four sides equal in length and all four interior angles measuring 90 degrees.
Answer: D. Line segment
Explanation: A line segment is a portion of a line that is bounded by two specific endpoints, unlike a line which extends infinitely in both directions.
Answer: C. Obtuse angle
Explanation: An obtuse angle is wider than a right angle but not as wide as a straight line, falling between 90 and 180 degrees.
Answer: A. Triangle
Explanation: A triangle is a two-dimensional polygon defined by having exactly three straight sides and three interior angles that sum to 180 degrees.
Answer: C. Equilateral
Explanation: An equilateral triangle is a special type of triangle where all three sides are the same length and all three angles are equal.
Answer: B. Line of symmetry
Explanation: A line of symmetry acts as a fold line; if you were to fold the shape along this line, the two halves would match perfectly.
Answer: B. Perpendicular lines
Explanation: Perpendicular lines are lines that cross each other specifically at a 90-degree angle, creating a perfect corner.
